Oxide-based high temperature proton exchange membrane fuel cells. Proton exchange membrane fuel cells (PEMFCs) are one of the most efficient energy conversion technologies for producing electricity from fuels such as hydrogen and methanol. Current PEMFCs use precious metal catalysts, and the performance of liquid methanol fuel is disappointingly low due to the inability of polymer or hybrid membranes to operate at temperatures above 160-180 degrees centigrade.

Proton exchange membrane fuel cells (PEMFCs) are one of the most efficient energy conversion technologies for producing electricity from fuels such as hydrogen and methanol. Current PEMFCs use precious metal catalysts, and the performance of liquid methanol fuel is disappointingly low due to the inability of polymer or hybrid membranes to operate at temperatures above 160-180 degrees centigrade. This work aims to develop an all oxide-based PEMFC technology using a recently developed sintered and heteropolyacid functionalised mesoporous silica membrane. The utilisation of all-oxide-PEMFCs using non-precious metal catalysts is expected to significantly enhance the power density, reduce costs, and enhance the commercial viability of PEMFC technologies.Read moreRead less
