Description
Technical field
The present invention relates to a kind of air penetrability method of testing and test pool and isolated plant, specifically a kind of method of testing of fuel cell membrane electrode air penetrability and test pool and proving installation.
Background technology
The energy and environment are two big key factors of human social development, and along with increasing and rapid development of economy of population, fossil energy will be petered out, and a large amount of consumption of fossil energy have caused the serious environmental pollution simultaneously.According to statistics, urban atmospheric pollution is mainly derived from automobile exhaust pollution.Therefore, the cleaning vehicle of research, development and utilization regenerative resource is realized energy variation, guarantees that national energy security and environmental protection are significant.
Fuel cell (Fuel Cell) is a kind of isothermal electrochemical generating unit that directly chemical energy is converted into electric energy, and it is not subjected to the restriction of Carnot cycle without the overheated machine process, energy conversion efficiency height (can reach 40～60%).Simultaneously, it also has eco-friendly advantage, discharges nitrogen and sulfur oxide hardly, and emission amount of carbon dioxide also reduces more than 40% than conventional power generation usage factory.Thereby, it is not only automobile one of the most promising alternative clean energy resource, can also be widely used in space shuttle, submarine, underwater robot, communication system, middle and small scale power station, domestic power supply, be fit to very much to provide mobile, decentralized power s again and supply with, and can solve the problem of peak load regulation network near terminal user's electric power.Also just because of above these outstanding superiority, fuel cell might become behind thermoelectricity, water power, nuclear power the 4th generation generation mode.
It is big that organic bath membrane cell (comprising Proton Exchange Membrane Fuel Cells, high temperature proton exchange film fuel cell and DMFC) has power density, advantages such as startup and response speed are fast are considered to one of optimal candidate power source of following automobile.The development FC-EV not only can reduce China's urban atmospheric pollution significantly, and to solving national energy security, realizes energy variation, develops national cleaning vehicle industry and fuel cell industry and has vital role.
Membrane electrode assembly is a core of forming fuel cell, and it is mainly by gas diffusion layers (being divided into anode gas diffusion layer and cathode gas diffusion layer), and Catalytic Layer (being divided into anode catalyst layer and cathode catalysis layer) and PEM are formed.
Air penetrability is one of important characterization parameter of characterization of membrane electrode life, and it is by the barrier property and the factors decisions such as film and Catalytic Layer combination degree of membrane material itself.Membrane electrode assembly will be by processes such as hot pressing in preparation process, improving contacting of Catalytic Layer and PEM, but PEM generation swelling in the hot pressing, thus the PEM air penetrability is increased; Simultaneously, in the process of compacting membrane electrode, catalyzer will partly cover the surface of film, can reduce the air penetrability of membrane electrode again accordingly.In addition, membrane electrode is in actual moving process, to tolerate the impact of different operating condition (as variation of on-stream pressure, humidification temperature, operating temperature and stoichiometric proportion etc.), cause the air penetrability of membrane electrode and PEM that bigger variation takes place, thereby can influence the performance and the life-span of membrane electrode and battery.When the air penetrability of membrane electrode increases to a certain degree, can cause the interior string of battery easily, thereby cause fuel and oxygenant to mix, the efficient of fuel cell is reduced.When the reaction velocity of fuel and oxygenant mixing is uncontrollable, can discharge a large amount of heats at short notice, cause burning or blast, cause danger.Thereby, in time, the air penetrability of test membrane electrode is most important effectively.
At present, the air penetrability of membrane electrode mainly calculates by the method for electrochemical method test fuel cell leakage hydrogen electric current.This method is only applicable to the saturating hydrogen amount of test membrane electrode.The influence that numerous factors such as electrostatic double layer, catalyst surface adsorbed state in the hydrogen current method test membrane electrode air penetrability process are leaked in the electrochemical method test is bigger, thereby the test data accuracy is reduced; And in test process, the adsorbing species of catalyst surface and the adsorbed state of species, purge time and electrochemical apparatus kind etc. all have considerable influence to the test result of the saturating hydrogen amount of membrane electrode.Thereby, the present invention proposes a kind of air penetrability method of testing and anchor clamps and proving installation of accurate and effective fuel cell membrane electrode; This method not only can avoid the electrochemical method test to leak the influence of numerous factors such as electrostatic double layer, catalyst surface adsorbed state in the hydrogen current method test membrane electrode air penetrability process, make test data more objective, accurate, and test process is simple, easily control, good reproducibility; This method is the air penetrability of off-line test membrane electrode exactly not only, also can online in real time detects the air penetrability of battery, the security that improves membrane electrode; In addition, this method can overcome the shortcoming that electrochemical method can only be tested the hydrogen air penetrability, the amount of saturating hydrogen, oxygen flow gas and air permeable that can the test membrane electrode.
