Fuel cell is a kind of chemical cell that chemical energy possessed by fuel is directly changed into electric energy, also known as electrochemical
Learn electric organ；It is the 4th kind of generation technology after hydroelectric generation, heat energy power-generating and nuclear electric power generation.Since fuel cell is logical
It crosses electrochemical reaction and the Gibbs free energy part in fuel chemical energy is converted into electric energy, not by the limit of Carnot cycle effect
System has very high economy.
The various fuel cells of actual motion at present consider further that the consumption of whole device system due to the limitation of various technologies
Can, total transfer efficiency such as considers waste heat utilization up to 80% or more mostly within the scope of 45%-60%.In addition, fuel cell fills
It sets without moving component, and reliable operation, maintenance is less, lower compared to sound for more traditional generating set.In addition, electrochemical
The harmful substance for learning reaction cleaning, safety and generation is less.Everything advantage all makes fuel cell be considered as one kind very
Promising energy source and power device.
Proton Exchange Membrane Fuel Cells is one kind of fuel cell, is equivalent to " inverse " device of hydrolysis electricity in principle,
Monocell by anode, cathode and membrane electrode assembly at.By taking hydrogen is the Proton Exchange Membrane Fuel Cells of fuel as an example, the anode of film battery

Point actual performance has larger difference, and membrane electrode each point heat production is inconsistent, is will lead in membrane electrode when serious and hot-spot occurs, very
To burn-through proton exchange membrane；On the other hand, if the water generated in fuel cell operation cannot exclude in time, liquid water slug
Runner will cause gas flow and be obstructed, and can not be uniformly distributed.Fuel battery negative pole plate flow field, anode plate flow field and cooling simultaneously
The pressure drop in flow field has a significant impact to the type selecting of blower, air pump and liquid pump.
The structure of bipolar plates directly determines the type of flow and distribution of fuel battery inside gas and coolant, thus directly
The electrochemical reaction and hydro-thermal management for influencing fuel battery inside are connect, while the structure of bipolar plates also directly determines bipolar plates portion
