METHOD FOR PRODUCING AND INTEGRATION OF DIRECT SODIUM BOROHYDRIDE FUEL CELL

摘要

In the related invention, for different applications, the system integration of a 70-150 W functional and portable direct sodium borohydride fuel cell (DSBHFC) is realized. The system is integrated in such a way that neither the hydrogen from the sodium borohydride fuel nor the oxygen from the oxidant hydrogen peroxide affects the fuel cell performance. The 70-150 W power system consists of 4 different groups. Each group has two stacks with 7 cells. Therefore, each group has a total of 14 cells. The system altogether has 56 cells. The fuel and the oxidant pumped from the storage tanks are sent to the distributing unit through the anode and cathode lines. In the distributor, anode and cathode flows distributed to every feeding line for each stack reach the cells through the distribution lines. The fuel and oxidant solutions in the stack reach the collecting units through the collecting lines. The flows are sent back form the collecting units to the feeding tank. In this way, the circulation of fuel and oxidant in tanks for each 7-cell group is realized and the performance is increased.
