Abstract
A fuel cell system is equipped with a drive motor, a fuel cell, and a controller. The controller performs normal electric power generation under a condition that the fuel cell is not warmed up, warm-up electric power generation with lower electric power generation efficiency than normal electric power generation, and controls performance of warm-up electric power generation on a basis of a predetermined index on a necessity to warm up the fuel cell. The controller controls an operation state of the fuel cell during warm-up electric power generation on a basis of a correlation between the system loss required for warm-up of the fuel cell and a warm-up output required for driving of a load including the drive motor during warm-up of the fuel cell.
