In a fuel cell utilizing an acid electrolyte, such as H3PO4, the electrolyte retaining matrix is made from silicon carbide. The silicon carbide has been found to be virtually inert to H3PO4 at fuel cell operating temperatures and provides all the other necessary and desirable matrix properties. This matrix is expected to have a life of at least 40,000 hours under normal fuel cell operating conditions.
