Abstract
The present invention relates to a fuel-cell system. This system includes an anode electrode; a cathode electrode; a separator positioned between the anode electrode and the cathode electrode, wherein the separator is not an ion exchange membrane; an anode catalyst; and a cathode catalyst, wherein the cathode catalyst is a non-precious metal catalyst or metal-free catalyst. The present invention also relates to a method of generating energy from crude fuel. This method involves providing a fuel-cell system and contacting the fuel-cell system with a crude fuel under conditions effective to generate energy from the crude fuel.
