Abstract
In the process of preparing hydrogen by passing a gas containing carbon monoxide over one side of a membrane which transports ionic oxygen and by passing steam over the other side of said membrane whereby the steam is converted to hydrogen and the carbon monoxide is oxidized to carbon dioxide, the improvement which comprises employing as said membrane a metal salt where the metal cation is selected from metals of Groups IB, IIB, and VA, and the salt anion is an oxygen containing anion of a metal from Group VB, VIB, and VIIB.
