The anodic activity of anodic catalyst for borohydride oxidation reaction (BOR) and inhibiting the borohydride hydrolysis reaction (BHR) are crucial to development for direct borohydride fuel cells (DBFC). In this paper, binder free CoSnx‐B/Ni‐foam (x = 0, 0.33, 0.5, 1) anode catalysts for BOR were prepared by chemical reduction method. It is found that the tin (Sn) is favor for improving the catalytic...
IrCo bimetallic anode catalysts for polymer electrolyte membrane fuel cell (PEMFC) have been synthesized with a modified ethylene glycol method. X‐ray diffraction, TEM, CV, and linear sweep voltammetry results show that after the modification of Co, Ir nanoparticles supported on carbon exhibit high activity for hydrogen oxidation reaction (HOR). The maximum power density of 610.5 mW cm–2 of a 50 cm...
A direct borohydride fuel cell (DBFC) employing a polyvinyl alcohol (PVA) hydrogel membrane and a nickel‐based composite anode is reported. Carbon‐supported platinum and sputtered gold have been employed as cathode catalysts. Oxygen, air and acidified hydrogen peroxide have been used as oxidants in the DBFC. Performance of the PVA hydrogel membrane‐based DBFC was tested at different temperatures and...
