A heat utilization system according to the invention includes: a sealed container into which a hydrogen-based gas is supplied; a heat generating structure that is accommodated in the sealed container and includes a heat generating element that is configured to generate heat by occluding and discharging hydrogen contained in the hydrogen-based gas; and a heat utilization device that utilizes, as a heat source, a heat medium heated by the heat of the heat generating element. The heat generating element includes a base made of a hydrogen storage metal, a hydrogen storage alloy, or a proton conductor, and a multilayer film provided on the base. The multilayer film has a first layer made of a hydrogen storage metal or a hydrogen storage alloy and having a thickness of less than 1000 nm and a second layer made of a hydrogen storage metal or a hydrogen storage alloy, which is different from that of the first layer, or ceramics and having a thickness of less than 1000 nm.

Heat utilization system and heat generating device

Provided are a novel heat utilization system and heat generating device that utilize an inexpensive, clean, and safe heat energy source. A heat utilization systemincludes a heat-generating elementconfigured to generate heat by occluding and discharging hydrogen, a sealed containerhaving a first chamberand a second chamberpartitioned by the heat-generating element, and a temperature adjustment unitconfigured to adjust a temperature of the heat-generating element. The first chamberand the second chamberhave different hydrogen pressures. The heat-generating elementincludes a support elementmade of at least one of a porous body, a hydrogen permeable film, and a proton conductor, and a multilayer filmsupported by the support element. The multilayer filmhas a first layermade of a hydrogen storage metal or a hydrogen storage alloy and having a thickness of less than 1000 nm and a second layermade of a hydrogen a hydrogen storage metal different from that of the first layer, a hydrogen storage alloy different from that of the first layer, or ceramics and having a thickness of less than 1000 nm.
