Direct sodium borohydride fuel cell using ferrocene as cathode catalyst

Abstract

The invention relates to fuel cell technology, and aims at providing an immediate sodium borohydride fuel cell with ferrocene as a cathode catalyst. The immediate sodium borohydride fuel cell takes alkaline sodium borohydride water solution which contains 10wt% of NaBH4 and 5wt% of NaOH as a fuel, takes air or pure oxygen as an oxidant, and takes perfluorinated sulfonic acid resin as an electrolyte; an anode catalyst is one or a mixture of a plurality of components chosen from noble metal catalysts Pt, Pd, Au and Ag and alloys thereof and non-noble metal catalysts Ni, Fe, Co, Mn, Cr and Ti and alloys thereof, and hydrogen storage material MnNi5-xMx and Zr1-xTixNi2-yNy, wherein, the range of x is 0.01-0.5 and the range of y is 0.01-1.5; the cathode of the fuel cell takes the ferrocene as a cathode catalyst. The immediate sodium borohydride fuel cell has the beneficial effects that: the sodium borohydride has higher hydrogen storage density, the noble metals are not needed as the anode electrode catalysts when an electrochemical oxidation reaction is carried out, and the immediate sodium borohydride fuel cell has higher electromotive force and higher energy density, which can effectively reduce the cost of the fuel cell, solves the problem of lack of platinum resources, and is useful for the popularization of the fuel cell technology.
