  • Patent number: 11870118
    Abstract: A fuel cell system includes a fuel cell that generates power using a fuel gas and an oxygen-containing gas, a reformer including a vaporizing section and a reforming section, a raw fuel supply that supplies raw fuel, a reformed water supply that supplies reformed water, and a controller. The controller has multiple calculation formulas for calculating an amount of reformed water to be used in the reforming section in response to a requested power level from an external unit, and selects, based on an increase or a decrease in a requested current level from the external unit, a formula from the multiple calculation formulas in response to the increase in the requested current level, and a formula different from the formula to be selected for the increase from the multiple calculation formulas in response to the decrease in the requested current level.

  • Publication number: 20240006637
    Abstract: 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.

  • Patent number: 11742505
    Abstract: A fuel cell system includes a controller that controls an amount of air flow to be supplied from an air blower included in an oxygen-containing gas supply to a cell stack to cause a power level (in amperes) of a fuel cell controllable by a power level regulator (power conditioner) and an air utilization to have an increase-control section in which the air utilization increases in accordance with an increase in the power level of the fuel cell and a decrease-control section in which the air utilization decreases in accordance with an increase in the power level. The air utilization is a ratio of an air amount used by the fuel cell for power generation to an oxygen-containing gas (air) amount supplied to the fuel cell.
