HEAT RECOVERY SYSTEM AND HEAT GENERATING DEVICE Russian patent published in 2023 - IPC F24V30/00 F28D20/00 

FIELD: heat recovery and generation.

SUBSTANCE: heat recovery system 10 includes: sealed container 15 to which a hydrogen-based gas is supplied; heat generating structure 20 housed in sealed container 15, which includes a heat generating element for generating heat by absorbing and releasing hydrogen contained in the hydrogen-based gas; and heat recovery device 12 that uses a heat medium heated by the heat of the heat generating element as a heat source. 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 deposited on the base. The multilayer film includes the first layer made of a hydrogen storage metal or a hydrogen storage alloy and with a thickness of less than 1000 nm, and the second layer made of a hydrogen storage metal or a hydrogen storage alloy different from the metal or alloy of the first layer, or ceramic and having a thickness of less than 1000 nm.

EFFECT: invention provides a new heat recovery system and a heat generating device using an inexpensive, clean and safe source of thermal energy.
