Abstract
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.
