HYDROGEN DIFFUSION ELECTRODE FOR PROTONIC CERAMIC FUEL CELL

摘要

A proton conducting fuel cell that includes an electrolyte having a proton conducting ceramic electrolyte and a two-phase diffusion membrane electrode contacting the electrolyte, where the electrode is substantially non-porous and permeable to hydrogen. Also, a method of generating molecular hydrogen from a proton conducting fuel cell having a positive and negative electrode in contact with a proton conducting ceramic electrolyte, including selectively extracting pure hydrogen from a hydrogen gas mixture, and electrolyzing water vapor at a positive electrode of the fuel cell to form molecular oxygen (O₂) and hydrogen ions, and reducing the hydrogen ions at a negative electrode of the fuel cell to form molecular hydrogen (H₂).
