Publication number: 20240006637Abstract: A fuel battery module unit includes a fuel battery module and a controller. The fuel battery module includes a reformer and a fuel battery cell stack. The reformer generates fuel gas by reforming raw fuel gas. The fuel battery cell stack includes multiple fuel battery cells. The fuel battery cells generate power through a chemical reaction between the fuel gas generated by the reformer and an oxidant. The controller raises the temperature of the reformer from startup until start of generation of power in the fuel battery cell stack. The controller lowers the temperature of the reformer multiple times until the fuel battery cell stack starts generating power.Type: ApplicationFiled: September 17, 2021Publication date: January 4, 2024Inventors: Takuro WASHIO, Kazunari SUGIHARA, Kyosuke YAMAUCHI
