An electrochemical heat transfer device utilizes an electrochemical hydrogen compressor to pump hydrogen into and out of a reservoir having a metal hydride forming alloy therein. The absorption of hydrogen by the metal hydride forming alloy is exothermic, produces heat, and the desorption of the hydrogen from the metal hydride forming alloy is endothermic and draws heat in. An electrochemical hydrogen compressor may be configured between to reservoirs and pump hydrogen back and forth to form a heat transfer device. A heat exchange device may be coupled with the reservoir or may comprise the outer surface of the reservoir to transfer heat to an object or to the surroundings. A closed loop may be configured having two reservoirs and one or two electrochemical hydrogen compressors to pump the hydrogen in a loop around the system.

A solid-gas reaction substance-filled reactor includes a core part in which heat medium heat-transfer tubes and spacers are alternately stacked, a gas introduction/discharge part that communicates with opening ends of the spacers, and a heat medium introduction/discharge part that communicates with heat medium flow paths. Filled bodies including metallic foil bags and a solid-gas reaction substance filled in the bags are inserted into the spacers. At least the filled bodies and the heat medium heat-transfer tubes are brazed to each other. The solid-gas reaction substance-filled reactor is obtained by stacking the filled bodies with the solid-gas reaction substance filled into the metallic bags, the heat medium heat-transfer tubes, and the spacers in a predetermined order and then brazing them.

The invention relates to a method for executing an alternating evaporation and condensation process of a working medium on a heat transfer surface provided simultaneously as an evaporation and condensation surface. The method is characterized in that, during a respective operating cycle from in each case an condensation process and in each case an evaporation process, a condensate film of the working medium which forms during the condensation process is stored permanently in situ on the heat transfer surface and is then evaporated from the heat transfer surface during the evaporation process. In terms of the apparatus, the heat transfer surface (2) is in the form of an in-situ store for a condensate film (6) of the working medium which covers the heat transfer surface and does not drip off and remains on the heat transfer surface during the condensation process and evaporates during the evaporation process.
