Integrated power generation and chemical production using fuel cells
In various aspects, systems and methods are provided for operating a molten carbonate fuel cell with an excess of reformable fuel relative to the amount of oxidation performed in the anode of the fuel cell. Instead of selecting the operating conditions of a fuel cell to improve or maximize the electrical efficiency of the fuel cell, an excess of reformable fuel can be passed into the anode of the fuel cell to increase the chemical energy output of the fuel cell.

Abrasion resistant solid oxide fuel cell electrode ink
A method for forming a solid oxide fuel cell (sofc) includes co-firing the anode and cathode electrode layers, which involves placing an unfired anode onto a surface during the cathode print cycle. To avoid damage to the electrolyte and cathode production cycle by the green anode ink, an abrasion resistant ink is used to print the anode electrode layer..
