Fuel cell and cathode material |
摘要 |
A fuel cell includes an anode, a cathode and a solid electrolyte layer that is disposed between the anode and the cathode. The cathode includes a main phase and a sub phase. The main phase is composed mostly of perovskite oxide which is expressed by the general formula ABO 3 and includes at least Sr at the A site. The sub phase is composed mostly of strontium sulfate. An occupied area ratio of the sub phase in a cross section of the cathode is no more than 10.2%. |
