Abstract
© 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. As a potential solution to concerns on sustainable energy, the wide spread commercialization of fuel cell has long been hindered by limited reserves and relatively high costs of metal catalysts. 3D graphene, a carbon-only catalyst prepared by reduction of carbon monoxide with lithium oxide, is found to electrochemically catalyze carbohydrazide oxidation reaction efficiently. A prototype of a completely metal-catalyst-free anion exchange membrane fuel cell (AEMFC) with a 3D graphene anode catalyst and an N-doped CNT (N-CNT) cathode catalyst generate a peak power density of 24.9 mW cm-2. The average number of electrons electrochemically extracted from one carbohydrazide molecule is 4.9, indicating the existence of C-N bond activation, which is a key factor contributing to high fuel utilization efficiency.
