Abstract

An unsteady-state model was developed for a liquid-feed Direct Methanol Fuel Cell (DMFC) delivery considering two-phase system. The model considered the mass and heat transport in the feed delivery system attached to the anode and cathode of the fuel cell. The results were then compared with the experimental data from in-house fabricated DMFC and steady-state model. It was observed that the unsteady-state model gave more similar results with experimental data then the steady-state model. The effects of feed methanol concentration in the reservoir and current density on mass transport to the catalyst layer were revealed.
