Abstract
The power generation characteristic at room temperature of a single chamber fuel cell using a novel hydrated aluminium oxide, pseudoboehmite (pb) proton conductor as the electrolyte was studied based on dependence on the crystal structure and treatment temperature of pb electrolytes generated by the hot water treatment of Al and Al2O3 films evaporated on the glass substrate. A single fuel cell using the pb electrolyte could be fabricated in various gas mixtures of hydrogen and oxygen at room temperature. Maximum open circuit voltage was obtained at a fuel cell using pb electrolytes generated by the soak treatment of Al and Al2O3 films during 4 hours in the hot water of 90°C.
