In a high-concentration direct methanol fuel cell (HC-DMFC), the methanol crossover is typically decreased to an acceptable level by two main mechanisms: high methanol transport resistance between the anode reservoir and the membrane electrode assembly (MEA), and high water back flow from the cathod
The methanol and water crossover through the polymer electrolyte membrane (PEM) of the direct methanol fuel cell (DMFC) is analysed experimentally and theoretically. Crossover fluxes have been measured for different operating conditions using a miniplant with full online material balancing of all DM
