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.

Electrochemical device using thin micro-porous metal sheets. The porous metal sheet may have a thickness less than 200 m, provides three-dimensional networked pore structures of pore sizes in the range of 2.0 nm to 5.0 m, and is electrically conductive. The micro-porous metal sheet is used for positively and/or negatively-charged electrodes by providing large specific contact surface area of reactants/electron. Nano-sized catalyst or features can be added inside pores of the porous metal sheet of pore sizes at sub- and micrometer scale to enhance the reaction activity and capacity. Micro-porous ceramic materials may be coated on the porous metal sheet at a thickness of less than 40 m to enhance the functionality of the porous metal sheet. The ceramic coating layer of non-electrical conductivity can function as a membrane separator. The electrochemical device may be used for decomposing molecules and for synthesis of molecules such as synthesis of ammonia from water and nitrogen molecules.
