Fuel cell apparatus and method of controlling fuel cell apparatus
Abstract
A fuel cell apparatus includes a fuel cell connected directly to a load. An electricity accumulation circuit including an electricity accumulator is connected in parallel to the fuel cell. The electricity accumulator supplies electric power to the load when electric power supplied by the fuel cell is less than electric power that the load requires. The electricity accumulator is charged by regenerative power generated at the load and electric power output from the fuel cell. The fuel cell outputs electric power within a predetermined range.
