Fuel cell materials

Nowadays, proton conduction type of solid state oxide is developed for application of house, motorcar and cell phone, because it has high energy efficiency. Toshima is developing and synthesizing the solid state oxide materials by using some kinds of making process such as solid reaction, coprecipitation and sol-gel methods.
