IMPROVED SILICON CARBIDE MATRIX FOR FUEL CELLS

摘要

A matrix (16) for holding the electrolyte within a phosphoric acid fuel (12) is made from silicon carbide and a binder of polyethersulfone. Preferably the matrix consists of 10-20 weight percent polyethersulfone with a balance of silicon carbide. The matrix has improved strength, wettability and bubble pressure compared to the best known prior art matrix.
