Abstract

The purpose of this research is to develop an optimum of anode catalyst loading based on modified sulfonated poly(ether ether ketone) (SPEEK) with charged surface modifying macromolecules (cSMM) membrane. The preparation method of catalyst ink and membrane electrode assembly (MEA) was based on Dr. Blade method and hot pressing by using catalyzed diffusion media (CDM) method. The effect of 30% and 40% PtRu in 2, 4 and 6 mgcm^-2 of catalyst loading has been investigated with a fuel cell assembly. The optimization of anode catalyst loading will enhance the DMFC performance. It was found, the best optimal anode catalyst loading was 4 mgcm_-2 for this application. Therefore, 4 mgcm^-2 is the best catalyst loading.
