In one aspect of an inventive concept, a fuel cell system includes a cathode and an anode, a porous ceramic support positioned between the cathode and anode, and a molten electrolyte mixture in pores of the ceramic support. In another aspect of an inventive concept, a method for producing energy includes directing a gas stream through a cathode, where an inner side of the cathode is adjacent to a dual phase membrane including a ceramic support infiltrated with a molten electrolyte mixture, sweeping an outer side of the anode with water, where an inner side of the anode is adjacent to the dual phase membrane, and collecting energy from the anode. The dual phase membrane is sandwiched between the cathode and an anode.

Molten electrolyte dual-phase membranes for intermediate temperature fuel cells

A product includes a dilute alloy catalyst for carbon dioxide reduction. The catalyst has a majority component and at least one minority component. The majority component is present in a concentration of greater than 90 atomic percent of the catalyst. The majority component is copper, and each minority component is selected from the group consisting of: a transition metal, a main group metal, a lanthanide, and a semimetal.
