STACK FOR MIXED REACTANT FUEL CELL AND MIXED REACTANT FUEL CELL SYSTEM COMPRISING THE SAME

摘要

The present invention relates to a mixed injection fuel cell stack and a mixed injection fuel cell system including the at least one membrane including a polymer electrolyte membrane and an anode catalyst layer and a cathode catalyst layer positioned on both sides of the polymer electrolyte membrane. An electrode assembly and a plurality of conductive substrates, wherein the membrane-electrode assembly and the conductive substrate are stacked such that the membrane-electrode assembly is positioned between the conductive substrates, and the cathode catalyst layer is formed of iron-tetraphenylporphyrin (Fe- tetraphenylporphyrin (Fe-TPP), co-tetraphenylporphyrin (Co-TPP), iron-tetramethoxyphenylporphyrin (Fe-TMPP), cobalt-tetramethoxyphenylporphyrin (Co-tetramethoxyphenylporphyrin , Co-TMPP), iron-phthalocyanine (Fe-PC), cobalt-phthalocyanine (Co-phthalocyanin e, Co-PC), Ru-Mo-S, Ru-Mo-Se, Ru-W-S, and Ru-W-Se.;The stack for a mixed injection fuel cell of the present invention has a high activity, while the catalyst included in the cathode catalyst layer selectively acts only on the oxygen reduction reaction, thereby improving the performance of the mixed injection fuel cell system including the same. .; MIXED REACTANT FUEL CELL, Stack, Selective, Catalyst
