OXYHYDROGEN-SYSTEM FUEL CELL

摘要

PURPOSE:To make a noble metal catalyst unnecessary and eliminate the danger of explosion by introducing FeCl3 to the cathode to produce FeCl and HCl thereby performing electric power generation and oxidizing the thus produced FeCl2 solution containing HCl to regenerate FeCl3. CONSTITUTION:Hydrogen gas is introduced to the anode and an aqueous FeCl3 solution is introduced to the cathode. FeCl2 and HCl are produced in the cathode to perform intended electric power genetration. Air or oxygen is sent into an aqueous FeCl2 solution containing HCl produced in this process to oxidize Fe<2+> into Fe<3+> thereby regenerating FeCl3. With this fuel cell structure, the voltage decrease of the cathode is minimized and almost constant container voltage can be produced. Since only a little thermal energy is produced by voltage decrease, it is not necessary to provide this fuel cell with a cooling device.
