To provide a rolling bearing for fuel cell system capable of providing increased durability by suppressing the internal start point peeling accompanying white texture change caused by hydrogen of the rolling bearing incorporated in a force-feeding machine for force-feeding various types of fluid to devices in a fuel cell system and the fuel cell system capable of stably generating power over a long period of time.
This rolling bearing is incorporated in the force-feeding machine of the fuel cell system having at least a fuel cell stack and the force-feeding machine for transporting various types of fluid. A grease compound containing conductive substance of 0.1 to 10mass% or a grease compound substantially not containing sulphonate is sealed in the rolling bearing. The fuel cell system comprises the force-feeding machine having the rolling bearing for fuel cell system.
