Low Energy Pumps for Fuel Cells

This patented system integrates an electroosmotic (EO) pump into a fuel cell membrane electrode assembly (MEA) for low-energy management of liquid reactants and air. Conventional fuel cell air pumps consume a large fraction (~0.5) of the total energy produced by a fuel cell. The EO pumps have no moving parts so they can actively control MEA hydration and oxidizer diffusion with less work (
