Abstract

This report focuses on confirming the feasibility and on establishing the optimal operating conditions for a Direct Methanol Fuel Cell operated at high temperatures using a polybenzimidazole-based membrane electrode assembly. An MEA was subjected to various operating temperature and methanol concentrations. Tests were also conducted using an internal reforming layer contacting the anode. Results showed the performance of the cell increases with temperature up to 220 Celsius past which the MEA was damaged, showing reduced performance. The tests on the effects of concentration showed that at higher temperatures there is only a small dependence on methanol concentration and that at it is possible to operate close to the stoichiometric feed of methanol and water.
