Microfabricated Fuel Cell with Composite Glass/Nafion Proton Exchange Membrane

摘要

The performance of microfabricated fuel cells with Nafion-coated glass composite membranes was investigated. The performance and durability of the fuel cells with silica glass membranes were improved by casting a thin-film of Nafion on the anode side of the thin, phosphosilicate glass membrane. Nafion increased the strength of the glass membrane and provided a better chemical environment for the air-cathode. The use of a two-layer anode catalyst improved the anode performance by increasing the catalyst loading while maintaining catalyst porosity for proton transport.
