Description

燃料电池低温快速启动***及其启动方法 技术领域  Fuel cell low temperature quick start system and startup method thereof
本发明涉及车载燃料电池***， 尤其涉及一种燃料电池低温快速启 动***及其启动方法。 背景技术  The present invention relates to a vehicle fuel cell system, and more particularly to a fuel cell low temperature quick start system and a method for starting the same. Background technique
为了适应瞬息万变的全天候、 全地区的工作条件， 车载燃料电池必 须具有良好的冷启动 （即低温启动）特性。 而冷启动最大的问题在于低 温下水生成水， 阻碍了氢气和空气在膜电极（MEA ) 内部的扩散和质子交 换膜燃料电池 PEMFC阴极生成水的排除， 从而造成冷启动的失败。 是 "保温" 与 "加热融水" 方法。 为了达到保温的目的一方面需要减少 电堆 （即燃料电池组） 与环境间的换热， 另外一方面需要在停机以后向 电堆补充热量以使得电堆的温度维持在零度以上。 例如通用汽车公司设 计了一种用于低温环境的燃料电池能量管理***， 在需要加热的时候氢 气阀门和空气压缩机开启使一部分燃料电池开始工作， 产生的电能使加 热器开始对电堆和冷却液加热。 日产汽车公司设计了一种根据环境温度 的历史记录和使用者输入的待机时间而自动在保温和加热状态间切换热 管理***。  In order to adapt to the ever-changing all-weather, all-region working conditions, on-board fuel cells must have good cold start (ie low temperature start) characteristics. The biggest problem with cold start is that water generates water at low temperatures, hinders the diffusion of hydrogen and air inside the membrane electrode (MEA) and the removal of the cathode formed water from the PEMFC of the proton exchange membrane fuel cell, resulting in a cold start failure. It is the method of "insulation" and "heating and melting". In order to achieve the purpose of heat preservation, on the one hand, it is necessary to reduce the heat exchange between the stack (ie, the fuel cell stack) and the environment, and on the other hand, it is necessary to add heat to the stack after the shutdown to maintain the temperature of the stack above zero. For example, General Motors has designed a fuel cell energy management system for low temperature environments. When heating is required, the hydrogen valve and air compressor are turned on to start a part of the fuel cell, and the generated electric energy causes the heater to start to stack and cool. Liquid heating. Nissan Motor Co. has designed a system to automatically switch between thermal and heating states based on historical temperature history and user input standby time.
用于加热的热源可以 #居来源分为两大类： 一类为外部热源， 这种 热量主要在电堆外部产生通过导热介质传递到电堆和各个子***。 另外 一类为内部热源， 这种热量主要在电堆内部产生， 比如催化层上产生的 化学反应热或者氢气在气体流道内燃烧产生的热量。 例如日产公司设计 了一种燃烧室将氢气燃烧， 并通过换热器把生成的热量带入冷却液体循 环***， 通过冷却液体对电堆进行加热。 但是这种加热方式降低了燃料 的经济性， 增加了***的体积、 质量和生产成本。  The heat source used for heating can be divided into two categories: one is an external heat source, and this heat is mainly generated outside the stack through the heat transfer medium to the stack and the various subsystems. The other type is the internal heat source, which is mainly generated inside the stack, such as the heat of chemical reaction generated on the catalytic layer or the heat generated by the combustion of hydrogen in the gas flow path. For example, Nissan designed a combustion chamber to burn hydrogen, and the heat generated by the heat exchanger was introduced into the cooling liquid circulation system, and the stack was heated by the cooling liquid. However, this heating method reduces fuel economy and increases the size, quality and production cost of the system.
中国发明专利 200610134075. 4公开了一种燃料电池低温启动的方法 及装置， 将燃料电池与直流电源串联， 双向开关控制器可选择燃料电池 与负载或直流电源相连。 燃料电池 ^温启动时， 燃料电池与直流电源相 连， 氢气、 空气分别通入阳极和阴极， 调节电流、 电压控制器使一定的 电流通过燃料电池。 氢泵作用， 氢气在阴极产生， 氢气与空气中的氧气 反应放热， 使膜电极快速升温达到燃料电池能正常启动运行温度。 该发 明属于上述提到的 "加热融水" 方法， 通过增加额外的附属设备， 达到 快速启动的目的。 Chinese invention patent 200610134075. 4 discloses a method and a device for starting a low temperature of a fuel cell, the fuel cell is connected in series with a direct current power source, and the bidirectional switch controller can select a fuel cell. Connect to a load or DC power supply. When the fuel cell is warmed up, the fuel cell is connected to the DC power source, and hydrogen and air are respectively connected to the anode and the cathode, and the current and voltage controllers are adjusted to pass a certain current through the fuel cell. Hydrogen pump action, hydrogen is generated at the cathode, and hydrogen reacts with oxygen in the air to exotherm, so that the membrane electrode is rapidly heated to reach the normal starting operating temperature of the fuel cell. The invention belongs to the above-mentioned "heating and melting" method, and the purpose of quick start is achieved by adding additional accessory equipment.
综上所述， 现有技术均需增加额外的附属设备， 既增加了车载燃料 电池***的体积和重量， 又增加了成本， 而且会消耗额外的燃料， 降低 了燃料的经济性。 发明内容  In summary, the prior art requires additional accessory equipment, which increases the size and weight of the on-board fuel cell system, increases the cost, and consumes additional fuel, which reduces fuel economy. Summary of the invention
鉴于以上所述现有技术的缺点， 本发明的目的在于提供一种无需增 加额外附属设备的燃料电池低温快速启动***及其启动方法， 缩短在低 温条件下燃料电池的启动时间， 迅速达到燃料电池正常工作状态， 以保 证燃料电池汽车的正常启动。  In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a low-temperature quick-start system for a fuel cell without an additional accessory device and a starting method thereof, which can shorten the starting time of the fuel cell under low temperature conditions and quickly reach the fuel cell.

图 2 示出了本发明燃料电池低温快速启动***的一种实施方式， 包 括空气压缩机 1和燃料电池组 2，空气压缩机通过一输气管 4与燃料电池 组相连， 空气压缩机的进气口连接有一进气管 3， 进气管上设有入口空气 阀 6， 燃料电池组的出气口连接有一排气管 5， 排气管上设有限压阀 7， 燃料电池组 3上设有用于检测燃料电池组内部温度的温度传感器， 燃料 电池组的出气口还设有一支路管道 8与空气压缩机的进气口 3相连， 使 空气压缩机 1、 输气管 4、 燃料电池组 2及支路管道 8构成一循环回路， 并且支路管道上设有回路空气阀 9， 上述空气压缩机 1、 入口空气阀 6、 P艮压阀 7、温度传感器及回路空气阀 9均与一控制器连接，通过控制器控 制各部件的开关闭合运行等状态。 由于燃料电池在使用过程中必须对空 情况， 因此如若上次使用后没有进行 "扫水" 程序的话， 在低温环境下 会结水， 造成燃料电池冷启动的失败， 因此在低温情况下， 预热非常重 要。 如图 1 所示， 常规的燃料电池启动***中， 通过燃料电池组的空气 会通过排气管 5 直接排入外部环境的空气中， 尽管这部分压缩空气与低 温的燃料电池组进行了热交换， 温度有所下降， 但其温度仍高于外部环 境空气的温度， 因此可以加以利用。 基于这一理念， 本发明通过将已通 过输气管 4连接的空气压缩机 1和燃料电池组 1上再连接一支路管道 8 构成循环回路， 将通过燃料电池组 2的空气返回至空气压缩机 1再次压 缩加以循环利用。  2 shows an embodiment of a low-temperature quick-start system for a fuel cell of the present invention, comprising an air compressor 1 and a fuel cell stack 2, the air compressor being connected to the fuel cell stack via a gas pipe 4, the intake of the air compressor An intake pipe 3 is connected to the port, an inlet air valve 6 is arranged on the intake pipe, an exhaust pipe 5 is connected to the air outlet of the fuel cell stack, a pressure limiting valve 7 is arranged on the exhaust pipe, and a fuel cell stack 3 is provided for detecting fuel. The temperature sensor of the internal temperature of the battery pack, the gas outlet of the fuel cell stack is further provided with a pipeline 8 connected to the air inlet 3 of the air compressor, so that the air compressor 1, the gas pipeline 4, the fuel cell stack 2 and the branch pipeline 8 constitutes a circulation loop, and the branch pipeline is provided with a loop air valve 9, and the air compressor 1, the inlet air valve 6, the P pressure valve 7, the temperature sensor and the return air valve 9 are all connected with a controller. The controller controls the state of the switch closing operation of each component. Since the fuel cell must be in an empty condition during use, if there is no "sweeping" procedure after the last use, water will be formed in a low temperature environment, causing a failure of the cold start of the fuel cell, so at low temperatures, Heat is very important. As shown in Fig. 1, in a conventional fuel cell starting system, air passing through the fuel cell stack is directly discharged into the air of the external environment through the exhaust pipe 5, although this portion of the compressed air is heat-exchanged with the low-temperature fuel cell stack. The temperature has dropped, but its temperature is still higher than the temperature of the external ambient air, so it can be used. Based on this concept, the present invention forms a circulation loop by reconnecting the air compressor 1 and the fuel cell stack 1 connected through the gas pipe 4 to the circulation circuit, and returns the air passing through the fuel cell stack 2 to the air compressor. 1 again compress and recycle.
以下结合燃料电池低温快速启动***的启动方法作进一步详述。 预 热阶段： 根据现有技术已知， 经过压缩后的空气， 温度会升高， 因而可 以在通过燃料电池组时对其进行预热。 而且压缩空气与其他流体的热量 传递相比较， 压缩空气的热量传递到催化剂反应表面的路径较短， 传热 速率快，在本发明中可以直接利用燃料电池本身的附属设备空气压缩机 1 对空气进行压缩。 首先通过控制器打开入口空气阀 6及回路空气阀 9， 并 关闭限压阀 7， 经过进气管 3上设置的过滤器 10过滤杂质后的空气进入 空气压缩机 1 进行压缩， 而且为了提高压缩后空气的温度， 优选用绝热 压缩。 压缩后的空气通过输气管 4进入燃料电池组 1传递热量进行预热， 从燃料电池组 2流出的空气通过支路管道 8流回空气压缩机 1，再次进行 压缩并循环， 当温度传感器检测到燃料电池组 1 的温度达到 （TC及以上 时， 将此信号反馈给控制器， 控制器控制入口空气阀 6 关闭， P艮压阀 7 及回路空气阀 9的状态不变。 The following is further detailed in connection with the startup method of the fuel cell low temperature quick start system. Pre Thermal stage: It is known from the prior art that the temperature of the compressed air rises so that it can be preheated as it passes through the fuel cell stack. Moreover, compared with the heat transfer of other fluids, the heat transfer of the compressed air to the reaction surface of the catalyst is short, and the heat transfer rate is fast. In the present invention, the auxiliary device of the fuel cell itself can be directly used. Compress. First, the inlet air valve 6 and the return air valve 9 are opened by the controller, and the pressure limiting valve 7 is closed, and the air filtered through the filter 10 provided on the intake pipe 3 is introduced into the air compressor 1 for compression, and in order to improve the compression. The temperature of the air is preferably compressed by adiabatic. The compressed air enters the fuel cell stack 1 through the gas pipe 4 to transfer heat for preheating, and the air flowing out of the fuel cell stack 2 flows back to the air compressor 1 through the branch pipe 8, and is again compressed and circulated, when the temperature sensor detects When the temperature of the fuel cell stack 1 reaches (TC and above, this signal is fed back to the controller, the controller controls the inlet air valve 6 to close, and the state of the P pressure valve 7 and the return air valve 9 remain unchanged.
本发明燃料电池冷启动分为两个阶段。 燃料电池冷启动初期： 预热 后， 燃料电池组 1会进入一段时间的緩慢工作状态。 此时燃料电池组经 过几次循环后， 温度逐渐升高， 以达到越来越好的预热效果。 之所以在 启动初期还能对空气循环压缩使用的原因在于， 启动初期时供给燃料电 池组的空气过量系数可达 = ， 远远大于正常工作时的空气过量系数 = 1。 而且为了保险起见， 本发明中空气压缩机 1 上设有氧传感器对空 气压缩机进气口处的氧气含量进行检测， 并将检测的氧气含量值与控制 器中的预设值（优选氧气含量值不低于 17% )比较， 如若氧气含量值低于 预设值时，控制器打开入口空气阀 6，补充一部分新鲜的空气，与此同时， P艮压阀 7也会打开， 将一部分循环空气从排气管 5排出； 当氧气含量值 高于预设值时， 控制器控制入口空气阀 6及限压阀 Ί关闭。 这样双重保 障， 使得在冷启动初期压缩空气中的氧气含量始终维持在合理的范围之 内。  The cold start of the fuel cell of the present invention is divided into two stages. Initial stage of cold start of fuel cell: After preheating, fuel cell stack 1 will enter a slow working state for a period of time. At this point, after several cycles of the fuel cell stack, the temperature is gradually increased to achieve an increasingly better preheating effect. The reason why the air circulation can be compressed at the initial stage of startup is that the air excess coefficient of the fuel supply group at the initial stage of startup can reach =, which is much larger than the air excess coefficient = 1 during normal operation. Moreover, for the sake of safety, the air compressor 1 of the present invention is provided with an oxygen sensor for detecting the oxygen content at the air inlet of the air compressor, and the detected oxygen content value and the preset value in the controller (preferably the oxygen content) The value is not less than 17%.) If the oxygen content is lower than the preset value, the controller opens the inlet air valve 6 to replenish a part of fresh air. At the same time, the P pressure valve 7 is also opened, and a part of the cycle is cycled. The air is exhausted from the exhaust pipe 5; when the oxygen content value is higher than a preset value, the controller controls the inlet air valve 6 and the pressure limiting valve Ί to close. This double protection keeps the oxygen content of the compressed air at a reasonable level during the initial cold start.
燃料电池冷启动后期： 当燃料电池组 2进入正常工作状态后， 入口 空气阀 6保持打开状态， 回路空气阀 9关闭。 因正常工作状态下， 不同 设备上燃料电池的具体型号、 规格不同而导致所需正常工作压力相应不 值反馈到控制器， 通过控制器控制限压阀 7来维持正常工作压力。 Late stage of fuel cell cold start: After the fuel cell stack 2 enters the normal working state, the inlet air valve 6 remains open and the circuit air valve 9 is closed. Due to the different models and specifications of the fuel cells on different equipments under normal working conditions, the required normal working pressure is not corresponding. The value is fed back to the controller, and the pressure limiting valve 7 is controlled by the controller to maintain the normal working pressure.
综上所述， 本发明在不增加过多额外附属设备和不消耗额外燃料的 情况下， 通过设置一支路管道使空气压缩机和燃料电池组接通循环回路， 使排出燃料电池组的空气回到空气压缩机继续压缩升温， 并再次进入燃 料电池组循环加热， 而且温度更高， 以达到使燃料电池在低温条件下迅 速冷启动的目的。 所以， 本发明有效克服了现有技术中的种种缺点而具 高度产业利用价值。  In summary, the present invention allows the air compressor and the fuel cell stack to be connected to the circulation loop by setting a branch pipe without adding excessive additional auxiliary equipment and without consuming additional fuel, so that the air of the fuel cell stack is discharged. Returning to the air compressor to continue to compress the temperature rise, and again into the fuel cell cycle heating, and the temperature is higher, in order to achieve the purpose of rapid cold start of the fuel cell under low temperature conditions. Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.
