| Research Abstract |
Proton conducting phosphoric glassy electrolyte was investigated. It is found that the interface between glassy phase and micro crystalline particle generated in the glass matrix enhances the proton conductivity. This result provides a principle of a material design for a fast proton conductor working at around 150-300℃. We also investigated electro-oxidation of alcohols such as ethanol, ethylene glycerol and glycerol, using an intermediate temperature fuel cell working at around 250℃. It is observed that the alcohols can be oxidized rapidly at the intermediate temperature. The reaction mechanisms were also calcified through the electrochemical measurements.
