ABSTRACT:
A structure of fuel cell assembly is disclosed. A flow channel plate with a plurality of flow fields is respectively disposed on two sides of a fuel cell unit. A plurality of graphic electrodes is arranged on two sides of the fuel cell unit and the flow field matches the graphic electrodes. Thus water generated from reaction of the fuel cell is removed and further reduction of the performance of the fuel cell is avoided. Moreover, fuel is distributed more uniformly over reaction area of the cell. And the number of fuel cells stacked per unit volume is increased. Therefore, the efficiency of the fuel cell is improved.
