Abstract
A voltage estimation device includes a voltage acquisition unit that acquires an output voltage output by a first cell group containing one or more unit cells and one or more dummy cells, the unit cells and the dummy cells being connected in series, the unit cells being configured to generate electric power using a fuel gas and an oxygen-containing gas, the dummy cells being configured not to generate electric power, and a voltage estimation unit that estimates a cell voltage of each unit cell based on the output voltage and a unit amount of voltage drop per dummy cell.
Claims9
A voltage estimation device comprising one or more processors that execute computer-executable instructions stored in a memory, wherein the one or more processors execute the computer-executable instructions to cause the voltage estimation device to:
- acquire an output voltage output by a first cell group containing one or more unit cells and one or more dummy cells, the unit cells and the dummy cells being connected in series, the unit cells being configured to generate electric power using a fuel gas and an oxygen-containing gas, the dummy cells being configured not to generate electric power;
- and
- estimate a cell voltage of each of the unit cells based on the output voltage and a unit amount of voltage drop per dummy cell.
