Describe how a fuel cell converts the chemical energy of hydrogen or methanol directly into electricity, and write the half-equations at each electrode in acidic and alkaline electrolytes as well as the overall reaction.
In a molten carbonate fuel cell the mixture of hydrogen and carbon dioxide from the reaction is fed to the anode, while a mixture of oxygen and carbon dioxide is fed to the cathode. Carbonate ions, , move through the molten electrolyte from the…
Suggest why a molten carbonate fuel cell running on this gas mixture is considered to have a low environmental impact.
