Abstract: A hydrogen production system includes: cell stacks to produce hydrogen by electrolyzing water using supplied power; and a control unit. The control unit controls at least one specific cell stack of the cell stacks. The control unit selectively executes a load adjustment control to adjust a voltage or current of the power supplied to the specific cell stack, based on the amount of hydrogen production required for the entirety of the cell stacks, and an ON/OFF control to turn ON or OFF the power supplied to the specific cell stack.

Abstract: An actuator capable of attaining high output. The actuator includes a frame structure part that forms a frame structure surrounding a housing part, and a volume change part housed in the housing part. The volume change part increases a volume thereof by input of external energy. The frame structure part has a higher Young's modulus than a Young's modulus of the volume change part. The housing part has an anisotropic shape, with a maximum width in first direction of the housing part longer than a maximum width in second direction different from the first direction of the housing part.
