Direct Methanol Fuel Cell Battery Replacement Program

Abstract

Lifetime DMFC performance degradation studies were performed using both single cell and high throughput catalyst screening techniques. Efforts to mitigate the degradation of the DMFC were focused on acid pre-treatment of the anode catalyst, identification of novel anode catalyst materials, load cycling techniques, and improvement of the catalyst layer deposition. Acid pre-treatment of the anode catalyst yielded no significant decrease in the time dependent performance degradation. No performance improvement was identified using the novel catalysts developed or with the load cycling methods. The employment of a membrane catalyst deposition technique demonstrated superior performance over direct gas diffusion layer catalyst deposition.
