Problems solved by technology

At present, research on low-cost catalysts mainly focuses on transition metal atom cluster catalysts, macrocyclic compound catalysts containing transition metals in the center, and metal carbide catalysts; in addition, nitrides, sulfides, borides, and silicides are used as low-temperature fuels. Battery catalysts have also been reported, but the performance of these catalysts is relatively poor, and there are relatively few studies

Abstract

The invention relates to a fuel cell technology, and aims at providing a hydrogen fuel cell with ferrocene as a cathode catalyst. The hydrogen fuel cell takes pure hydrogen as a fuel, and takes air or pure oxygen as an oxidant, 6NKOH or takes perfluorinated sulfonic acid resin as an electrolyte, and takes platinum carbon as an anode catalyst, and the cathode of the fuel cell takes the ferrocene as the cathode catalyst. The hydrogen fuel cell of the invention has the beneficial effects that: by replacing the platinum with the ferrocene as the cathode catalyst of the fuel cell, the cost of the hydrogen fuel cell can be effectively lowered, the problem of the short platinum resources can be solved, and the hydrogen fuel cell is useful for the popularization of the fuel cell technology.
