ABSTRACT:
A single chamber fuel cell comprised of a cell arranged in a mixed fuel gas comprised of hydrogen or another fuel gas and oxygen, wherein the cell used is a pn junction type semiconductor having electrodes of a p-type semiconductor with carriers of holes and an n-type semiconductor with carriers of electrons connected to ends of electrical takeout wires, and each of the p-type semiconductor and n-type semiconductor is formed porous to an extent enabling the mixed fuel gas to pass.
