A typical battery stack generally includes: the water conservancy diversion import and the flow-guiding channel of (1) fuel and oxidant gas are distributed to fuel (as hydrogen, methyl alcohol or the hydrogen-rich gas that obtained by methyl alcohol, natural gas, gasoline) and oxidant (mainly being oxygen or air) in the guiding gutter of each anode, cathode plane equably after reforming; (2) import and export and the flow-guiding channel of cooling fluid (as water) are evenly distributed to cooling fluid in each battery pack inner cooling channel, the heat absorption that hydrogen in the fuel cell, the exothermic reaction of oxygen electrochemistry are generated and take battery pack out of after dispel the heat; (3) outlet of fuel and oxidant gas and corresponding flow-guiding channel, fuel gas and oxidant gas are when discharging, and portability goes out the liquid that generates in the fuel cell, the water of steam state.Usually, the import and export of all fuel, oxidant, cooling fluid are all opened on the end plate of fuel battery or on two end plates.
Proton Exchange Membrane Fuel Cells can be used as the dynamical system of delivery vehicles such as all cars, ship, can make portable, portable, fixed Blast Furnace Top Gas Recovery Turbine Unit (TRT) again.
Proton Exchange Membrane Fuel Cells is generally with hydrogen or contain portly hydrogen or alcohols is made fuel.As car, ship power system or movable type, stationary power generation station the time, generally use air oxidant.
When used in proton exchange membrane fuel cell is done car, ship power system or movable type, stationary power generation station, must comprise battery pile, supply of fuel, air supply, cooling heat dissipation, control and electric energy output various piece automatically.Wherein air supply is essential.Electrochemical reaction in the Proton Exchange Membrane Fuel Cells improves along with the pressure of fuel, oxidant air and accelerates.
