Abstract
Two methods of hydrogen separation using proton-conducting perovskites, electrochemical hydrogen pumping with proton-conducting electrolytes and hydrogen sieving through protonic-electronic mixed conductors, are stated. In the former case, high temperature proton conductors (HTPCs) enable the hydrogen transport by external application of electricity. In the latter case, it is a fundamental concern how the protonic and electronic charge carriers coexist in oxides to allow hydrogen permeation. Experimental results and the problems for future investigations are discussed.
