This communication reports on the fabrication of membrane electrode assemblies (MEAs) for low temperature direct methanol fuel cells (DMFCs) using PVA-PAMPS proton-conducting semi-IPN membranes. New types of proton conducting polymers PAMPS, PVA/PAMPS and PVA/PAMPS/PEGDCE of similar chemical nature were tested as both the catalyst ink and the binder for MEA fabrications in place of traditional Nafion solutions. MEAs fabricated with PVA/PAMPS binder achieved not only the improved cell performance but also a good durability comparable to those fabricated with Nafion solution. Performance in DMFC mode with PVA/PAMPS/PEGDCE proton-conducting semi-IPN membrane showed a power density of 19.5 mW cm−2 at 25°C and increased to 49.7 mW cm−2 at 80°C with a metal loading on the anode of 2 mg cm−2.
