Abstract:
The passive direct methanol fuel cell (PDMFC) are promising option for powering advanced electronic devices in the future due to the high power densities, easy fuel storage, low operatingtemperature, low noise level and simple design [1]. Fuel crossover is one of the major problems in the fuel cell performance which causes reduction in fuel utilization and occurrence of mixed potential in cathode compartment [2]. Using non-reactive catalyst to fuel in cathode is one of theinteresting methods to decrease fuel crossover effect. The aim of the present work is to investigate the performance of a PDMFC with application of nitrogen-doped graphene (NG) as cathode electrocatalyst which is highly selective to oxygen inpresence of methanol. The results demonstrated that the PDMFC with NG has better performance compared to commercial Pt/C as cathode electrocatalyst.
