Description
Technical Field

Background
Fuel cells are promising new power sources, generally using hydrogen, carbon, methanol, borohydride, gas or natural gas as fuel, as the negative electrode, and oxygen in air as the positive electrode. The main difference from a general cell is that the active material of the general cell is pre-placed inside the cell, and thus the cell capacity depends on the amount of active material stored, while the active materials (fuel and oxidant) of the fuel cell are continuously fed while reacting, so that such a cell is actually just an energy conversion device. The battery has the advantages of high conversion efficiency, large capacity, high specific energy, wide power range, no need of charging and the like.

Electrode plates are an important component of a typical hydrogen fuel cell stack, which serve both as current collector plates and as support membrane electrodes. The flow guide channels on the electrode plates are used for both the channels of fuel hydrogen and oxidant entering the surfaces of the anode and the cathode and the channels for taking away water generated in the operation process of the fuel cell.
