Methanol Fuel Cell

A one-dimensional two-phase model has been developed for a direct methanol fuel cell (DMFC) and flowing electrolyte - direct methanol fuel cell (FE-DMFC). The model has been compared to experimental data found in literature and corresponds well. Using this model, the performance of the DMFC and FE-DMFC are evaluated and compared to one another as well as to their respective single phase models. It has been found that there is a substantial difference between a two-phase and single phase model. Furthermore, the FE-DMFC outperformed the DMFC when it came to methanol inlet concentrations and varying operating temperatures due to the FE-DMFC’s ability to reduce the methanol crossover.

A two-phase model of an intermediate temperature (120–200 °C) proton exchange membrane (PEM) fuel cell is presented. This model accounts for two phase effects due to gas solubility in the phosphoric acid/PBI electrolyte, and considers aqueous phase electrochemical reactions. It accounts for all polarization and transport phenomena, and shows a good fit with experimental data in the temperature range (150–190 °C). This paper investigates catalyst utilization in intermediate temperature PEM fuel cells with phosphoric acid doped membranes. Simulations show that, under normal operation, 1–2% of the catalyst is utilized at both electrodes. Strategies are suggested to help reduce the cost of producing power from such systems.
