Abstract
A high performance ionomer assisted electrolytic cell electrode structure is provided. Such structures operate effectively at catalyst loadings as low as 0.10 mg/cm.sup.2 and demonstrate increased structural integrity without ionomer degradation. The inventive structure comprises a hydrated ion exchange membrane having a first surface and a second surface and at least one catalyst ionomer layer bonded to the first and/or second surface of the membrane that comprises hydrated and swollen ionomer solids bonded to discrete catalyst particles.
