In this program, Giner, Inc. advanced development of two types of direct methanol fuel cells for military applications. Advancements in direct methanol proton-exchange membrane fuel cell (DMPEMFC) technology included developement of a Pt-Ru anode catalyst and an associated electrode structure which provided some of the highest DMPEMFC performance reported to date. Scale-up from a laboratory-scale single cell to a 5-cell stack of practical area, providing over 100 W of power, was also demonstrated. Stable stack performance was achieved in over 300 hours of daily on/off cycling. Direct methanol aqueous carbonate fuel cells were also advanced with development of an anode catalyst and successful operation at decreased pressure. Improved materials for the cell separator/matrix and the hardware were also identified. (Author). 收起
