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 system 10 includes a heat-generating element 14 configured to generate heat by occluding and discharging hydrogen, a sealed container 15 having a first chamber 21 and a second chamber 22 partitioned by the heat-generating element 14, and a temperature adjustment unit 16 configured to adjust a temperature of the heat-generating element 14. The first chamber 21 and the second chamber 22 have different hydrogen pressures. The heat-generating element 14 includes a support element 61 made of at least one of a porous body, a hydrogen permeable film, and a proton conductor, and a multilayer film 62 supported by the support element 61. The multilayer film 62 has a first layer 71 made of a hydrogen storage metal or a hydrogen storage alloy and having a thickness of less than 1000 nm and a second layer 72 made 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.
