摘要： A humidity control device includes a condenser and a water absorber-drainer. The condenser has a first region and a second region. The first region is a region having hydrophilicity and where moisture is condensed. The condensed moisture is moved by gravity to the water absorber-drainer via the second region. The water absorber-drainer includes a temperature control member and has a water absorption surface and a water drainage surface. When a temperature of the water absorber-drainer is in a first temperature region, the water absorber-drainer absorbs through the water absorption surface the moisture moved from the condenser. When the temperature of the water absorber-drainer is controlled to be in a second temperature region by an operation of the temperature control member, the water absorber-drainer drains the absorbed moisture through the water drainage surface.

摘要： The present disclosure provides a thermoelectric conversion module that enables continued use of a thermoelectric generation system even when a part of a plurality of the thermoelectric conversion modules fails by being exposed to a higher temperature. The thermoelectric conversion module according to the present disclosure includes a substrate, a plurality of thermoelectric conversion element pairs electrically connected in series on the substrate, a pair of external terminals that carries out one of inputting and outputting of electric power, and a low melting point conductor. The low melting point conductor has a melting point that is substantially equal to a heat-resistant temperature of a p-type thermoelectric conversion element or an n-type thermoelectric conversion element. One of the pair of external terminals has a first connecting part connecting with the p-type thermoelectric conversion element positioned at one end of the plurality of thermoelectric conversion element pairs, whereas the other of the pair of external terminals has a second connecting part connecting with the n-type thermoelectric conversion element positioned at the other end of the plurality of thermoelectric conversion element pairs. The first and second connecting parts and the low melting point conductor are positioned in an inner region of the substrate. At least a part of the low melting point conductor is positioned between the pair of external terminals and is electrically insulated from at least one of the pair of external terminals.
