Side and cathode side constantly supply fuel (generally hydrogen) and oxidant (generally air), it can pass through redox
Reaction constantly externally exports electric energy.Unlike general rechargeable battery (such as lithium battery), a simple fuel electricity
Pond or fuel cell pile unit be it is inoperable, it needs the auxiliary system of a set of complexity to cooperate with it, constitutes a combustion
Material battery generating system could externally generate electricity.One typical fuel cell generation, other than fuel cell pile, one
As further include hydrogen supply Proton Exchange Membrane Fuel Cells be it is a kind of can the chemical energy being stored in fuel by electrochemistry it is anti-
As long as should be converted into the power generator of electric energy anode-side and cathode side constantly supply fuel (generally hydrogen) and
Oxidant (generally air), it constantly can externally export electric energy by redox reaction.With general charging electricity
Unlike pond (such as lithium battery), simple a fuel cell or fuel cell pile unit are inoperable, its need
The auxiliary system of a set of complexity is wanted to cooperate with it, constituting a fuel cell generation could externally generate electricity.One typical

When measure.In order to improve hydrogen utilization ratio and pile safety in operation, reaction remaining hydrogen is not directly discharged into atmosphere generally, but
Hydrogen pump is returned by using one, hydrogen unreacted on hydrogen circuit is positive from the direct blowback of fuel cell pile anode side outlet
Pole side entrance is participated in again into fuel cell after converging with the reaction gas of the fresh injection in inlet and is reacted.Fuel cell is just
During being often used, the nitrogen in pile cathode side reaction air and the generation water after reaction can pass through matter due to concentration difference
Proton exchange constantly to anode-side spread, cause the effective concentration of anode-side hydrogen constantly to reduce, influence reaction rate and
Performance data.In system design, an electromagnetism blow down valve can be generally added on pile anode-side export pipeline according to system
Control design case demand can be opened and closed periodically, by hydrogen partial, nitrogen and the water in hydrogen circuit periodically to big
Gas discharge, prevents the continuous accumulation of nitrogen and water in hydrogen circuit.
When ambient temperature is below the freezing point, and fuel cell system is closed, it is attached to liquid water-setting on hydrogen air-channel system
It build-ups ice, runner is blocked, cisco unity malfunction during fuel cell generation is cold-started, until the solid ice on runner is melted
Change.Could normally start, otherwise whole system can not normal cold-boot and operation, have much room for improvement.In addition, cooling circuit system
Can not can normally it start because ambient temperature is too low, empty air-channel system also can be because of the Air Temperature of the too low supply of ambient temperature
Degree is too low, influences the work of fuel cell.At low ambient temperatures, remain in fuel cell proton exchange after closing cell reaction heap
Water on film will freeze, and then destroy fuel battery proton exchange film.Simultaneously fuel cell optimum working temperature 60 DEG C-
Between 70 DEG C, the reliability of fuel cell is insufficient under low-temperature condition, and the waiting time started in low-temperature cool starting is too long, nothing
