Description
Technical field
The present invention relates to fuel cell field, particularly relate to the calorie control method of air-cooled fuel cell system coupling.
Background technology
Fuel cell is a kind of Blast Furnace Top Gas Recovery Turbine Unit (TRT) of electric energy that the chemical energy of reactive material converted to by electrochemical reaction, do not relate to the burning of fuel due to its power generation process, thereby not limited by Carnot cycle, energy conversion efficiency is high, and fuel cell is generally used hydrogen-oxygen as reactive material, also has power density and energy density is high, clean and effective, the advantage that power bracket is wide, be with a wide range of applications in fields such as portable power source, household electrical source, field of traffic, distributed power station and submarines.
Fuel cell utilizes electrochemical reaction that chemical energy is converted to electric energy, and this reaction is exothermic reaction, follows thermal release when producing electric energy.Take hydrogen and oxygen act as a fuel and the fuel cell of oxidant as example, the water that generates when reaction is gaseous state, the heat that reaction discharges is 241.8kJ/mol, if fuel cell monolithic operating voltage is 0.7V, the reaction heat except 135.4kJ is converted into electric energy, also has the reaction heat residue of 106.4kJ, therefore must control remaining heat, control fuel cell operation in suitable temperature range, to avoid battery operated too high or too low for temperature.
Typical complete fuel cell system take hydrogen as fuel not only comprises fuel cell pile, also should comprise the hydrogen storage unit.Storage hydrogen mode commonly used has three kinds at present: high-pressure hydrogen storing, liquefaction hydrogen storage and alloy storage hydrogen.Wherein the high-pressure hydrogen storing mode needs high pressure resistant reservoir vessel, general light-weight metal or the resin tank body of adopting adds the mode that Filament-wound Machine strengthens, can store the hydrogen of 1%-7%, Chu Qing is arranged, put hydrogen conveniently and the low advantage of cost, but hydrogen-storage density is little, and high pressure compressed hydrogen need consume 20% of institute's compression hydrogen contained energy; Low-temperature liquefaction storage hydrogen mode, the system hydrogen storage content can reach 16% left and right under atmospheric low-temperature, but liquefaction of hydrogen need be consumed 40% of liquefaction hydrogen contained energy, and exists the hydrogen container body complicated, need to keep low temperature, the deficiency that waits with high costs; As for alloy storage hydrogen mode, its hydrogen-storage density can reach 134gH
2/ L, far above the 17.9gH of high-pressure hydrogen storing
2The 70gH of/L and low-temperature liquefaction storage hydrogen
2/ L, and there is no the danger of blast and the loss problem of long term storage, but have the lower shortcoming of storage hydrogen mass density.
Hydrogen bearing alloy is usually used in fuel cell hydrogen-feeding, and hydrogen bearing alloy also is accompanied by the heat exchanging process of exothermic/endothermic in the reversible chemical reaction of inhaling hydrogen/put hydrogen.According to the difference of hydrogen bearing alloy kind, the heat of exchange is difference to some extent, for example LaNi
5Storage hydrogen thermal discharge be 30kJ/molH
2, Mg
2The storage hydrogen thermal discharge of Cu is 72.8kJ/molH
2Follow because hydrogen bearing alloy is this and inhale/put the exchange heat characteristic that the hydrogen process exists, the heat of just must consider that the alloy storage hydrogen device in fuel cell system stores up hydrogen, putting in the hydrogen process is controlled.
In the course of work of the typical fuel cells system that comprises fuel cell pack and alloy storage hydrogen device, when fuel cell reaction produces heat, the hydrogen bearing alloy release hydrogen absorbs heat, therefore, a kind of calorie control method of guaranteeing that two equipment can move normally and efficiently is necessary.For example the portable fuel battery equipment utilization fan of European patent EP 0917225A1 design passes to storage hydrogen device to the heat of fuel cell generation, makes storage hydrogen device stablize releasing hydrogen gas; Chinese patent ZL01807860.5 discloses a kind of heat control method of fuel cell system, do not use the auxiliary equipment such as fan, pump, the fuel cell first type surface is contacted with Chu Qing device outer wall direct heat or, by the heat-conduction medium thermo-contact, make the heat of fuel cell generation pass to storage hydrogen device; Chinese patent ZL200710175260.2 discloses a kind of design of coupled fuel cell, hydrogen storing unit is placed in the middle of two fuel cells, the heat that utilizes fuel cell reaction to discharge heats to hydrogen storing unit, utilize simultaneously the characteristic that hydrogen storing unit is put the hydrogen heat absorption to carry out the used heat that produces in absorption portion operation of fuel cells process, realize the coupling that heat is controlled.
But prior art is not all considered the impact of environmental condition on fuel cell system, and its heat control method can not adjust with the change of environmental condition, keeps system stability always and moves efficiently.when for example ambient temperature is low, storage hydrogen device release hydrogen needs heat, the normal operation of fuel cell simultaneously also needs certain heat to keep suitable working temperature, the existing passive heat control method that is coupled on hydrogen device and fuel cell structure of storing up by alloy is obviously not enough with regard to existing, in the time of storage hydrogen device release hydrogen, absorb endlessly the heat that fuel cell produces always, if battery is in the low power run stage (as startup stage), the heat that battery produces is original just few, most of heat is absorbed by storage hydrogen device again, just be not enough to keep normal working temperature, cause fuel battery temperature too low, operation (startup) difficulty, and heat that heat that hydrogen absorbs and fuel cell reaction produce not exclusively equates and the thermal loss of heat transfer process because hydrogen bearing alloy is put, passive heat control method can not guarantee the control precision of temperature of fuel cell, thereby can not guarantee that operation of fuel cells is in optimum temperature.during high ambient temperature, the environment hot-air can be used as hydrogen bearing alloy while putting hydrogen absorbs the thermal source of heat, storage hydrogen device is put hydrogen and is not had difficulties, the existing auxiliary equipment such as fan of utilizing just exists the heat control method that the fuel cell heat passes to storage hydrogen device obviously not enough, this moment, fuel cell optimum working temperature and the ambient temperature temperature difference were less, if keep fuel cell operation in optimum temperature, can only strengthen the rotating speed of fuel cell fan, to increase air mass flow, the waste heat that fuel cell produces is discharged, avoid fuel cell overheated, but the problem that the membrane electrode that can bring thus fuel cell is dried, and then cause fuel cell performance decay.
