Abstract:

Direct methanol fuel cells use methanol directly as a fuel, rather than the reformate typically required by fuel cells, thus eliminating the reformer and fuel processing train. 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 onoff 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 separatormatrix and the hardware were also identified.
