ABSTRACT:
A fuel cell system comprising a first electrode-electrolyte assembly having a first electrode coupled to one side of thereof and a second electrode coupled to a generally opposite side of the first electrode-electrolyte assembly, and a first conduit for delivering fuel to the first electrode at ambient temperature. The fuel cell system includes a second electrode-electrolyte assembly having a third electrode coupled thereto assembly, and a fourth electrode coupled to a generally opposite side of the second electrode-electrolyte assembly; and a mesh positioned between and in sealing engagement with the second electrode and the third electrode. A second conduit is in fluid communication with the fourth electrode for delivering oxidant thereto. The fuel cell system further includes means for providing an electrical potential across the first electrode-electrolyte assembly and an electrical load circuit for using an energy output generated across the second electrode-electrolyte assembly.
