PEFCにおける同一電極内水管理法の検討

抄録

Our laboratory has proposed Self-Water Management Separator (SWMS) with a bypass channel in the separator to progress the system efficiency and reduce the system cost. Because SWMS improves water-management- issue of Polymer Electrolyte Fuel Cells (PEFC) by reusing water generated within the same cell, it can achieve the improvement and the lowering the cost of efficiency. This study aims to select the optimum packing material from polyvinyl alcohol (PVA) sponge, diatomite powder, cellulose fiber insulation, and EM diatomite grain. Therefore, we selected PVA from viewpoints of cell performance and handling ability.
