Abstract
Preparation of catalyst layer in PEMFC electrodes was investigated. Toray carbon paper was used as diffusion layer, and Johnson-Matthey 20% Pt/C was employed as catalyst. Electrode contains neither PTFE nor carbon powder. The optimal catalyst layer composition was discovered by orthogonal test method, with the use of cell voltage-current curve and cyclic voltammogram curve. The optimal amount of the Nafion (ionomer) in the catalyst layer was found to be 1.4mg/cm2 when Pt loading was kept at 0.4mg/cm2. Power density of PEMFC achieved 0.37W/cm2 with air and H2 were used at the outlet pressure of 0.1Â MPa.
