Electrochemical Behavior of Direct Methanol Fuel Cells Based on Acidic Silica - Sulfonated Polysulfone Composite Membranes

This paper discusses the study and manufacture of polymer electrolyte membranes for use in DMFCs at various operating temperatures. The sulfonating agent was trimethyl silyl chlorosulfonate, but silica was modified by treatment with chlorosulfonic acid at room temperature. At 60°C feeding 1M methanol solution at the anode and dry air at the cathode, both at atmospheric pressure, a maximum power density of 60 mW cm-2 was achieved at 60°C.

Preparation and Characterisation of Composite Sulfonated Polyether Ether Ketone for Direct Methanol Fuel Cells

Direct Methanol Fuel Cells (Derbyte), one of the primary components that was used to realize the commercialization of fuel cells in transportation and portable equipment, uses a proton exchange polymer electrolyte. Poly Ether Ketone is a thermoplastic material with a combination of physico-chemical and mechanical properties. It is a thermoplastic resin with a combination of physico-chemical and mechanical properties. Due to the improvement of proton conductivity and methanol permeability, the sPEEK/Cs-PWA membranes ware potential candidate for application of DMFC as a proton conductive membrane for application of DMFC.
