This study presents an improved TSR model for Direct Methanol Fuel Cell (DMFC) with mass and energy balance equations taking into account gas evolution in the anode channels. The TSR model includes a modified charge balance equation suitable for potentiostatic fuel cell operation mode. Polarization curves calculated with the improved TSR model agree with experimental data from the literature. The developed TSR model is able to approximate two-dimensional concentration, temperature, and current density profiles in DMFC with parallel flow field.

PTFE/Nafion (PN) membranes were fabricated for the application of moderate and high temperature proton exchange membrane fuel cells (PEMFCs), respectively. Membrane electrode assemblies (MEAs) were fabricated by PTFE/Nafion membranes with commercially available low and high temperature gas diffusion electrodes (GDEs).The influence of [ZrOCl2]/[Nafio wt. ratio of Nafion/ZrOCl2 solution on the membrane morphology of NFZrP and PEMFCs performance was investigated. And the influence of hybridizing silicate into the PN membranes on their direct methanol fuel cell (DMFC) performance and methanol crossover was investigated. Silicate in PN membranes causes reduction both in proton conductivity and methanol crossover of membranes. Due to the low conductivity of PTFE and silicate, PNS had a higher proton resistance than Nafion-112.The effects of introducing sub-μm porous PTFE film and ZrP particles into Nafion membranes on the DMFC performance were investigated. The influence of ZrP hybridizing process into NF membranes on the morphology of NFZrP composite membranes and thus on the DMFC performance was also discussed.
