Membrane electrode assembly

A process for producing hydrogen and oxygen from steam, comprising:

• providing a membrane electrode assembly (MEA) comprising at least one cathode, at least one anode, and an electrolyte, wherein said electrolyte has a three-dimensional spatial expansion, and said cathode is connected with the electrolyte at one surface, and said anode is connected with the electrolyte at the opposite surface, wherein said electrolyte comprises lithiated iron oxide (LiFeOx) and at least one carbonate;
• contacting the steam with the electrolyte;
• applying a voltage causing the steam to react with the electrolyte, whereby said lithiated iron oxide (LiFeOx) is oxidized, and hydrogen is formed in the area of the cathode;
• and
• reducing said lithiated iron oxide (LiFeOx) in the area of the anode to form oxygen.

A process for generating electric power from hydrogen and oxygen, comprising:

• providing a membrane electrode assembly (MEA) comprising at least one cathode, at least one anode, and an electrolyte, wherein said electrolyte has a three-dimensional spatial expansion, and said cathode is connected with the electrolyte at one surface, and said anode is connected with the electrolyte at the opposite surface, wherein said electrolyte comprises lithiated iron oxide (LiFeOx) and at least one carbonate;
• contacting oxygen with the electrode in the area of the cathode, reacting with iron and Li2O to LiFeO2 while taking up electrons;
• and
• reacting hydrogen with LiFeO2 at the anode to form steam (H2O), iron and Li2O while emitting electrons
• wherein electrons flow from the anode to the cathode.
