Abstract: An assembly for producing energy may include a fuel cell, a fluidic cell circuit configured to receive a first heat-transfer fluid and arranged at least partially around the fuel cell, a reversible thermodynamic system configured to alternatively: (i) evacuate the thermal energy produced by the fuel cell and transform it into mechanical energy through the first heat-transfer fluid, and (ii) input thermal energy to the fuel cell through the first heat-transfer fluid, wherein the thermodynamic system includes: (a) a fluidic thermodynamic circuit to receive a second heat-transfer fluid; (b) a first exchanger to exchange thermal energy between the fluidic thermodynamic circuit and the fluidic cell circuit; and (c) a second exchanger configured to exchange thermal energy between the fluidic thermodynamic circuit and an external source.

Abstract: A roller shutter for an opening leaf of a building, includes a retractable shut-off panel that moves between retracted and deployed positions, and a guide to selectively guide the panel a path between the retracted position and a deployed position in a first plane, and another path is a path between the retracted position and a deployed position in a second plane parallel to said first plane. The guide selectively switches movement of between said first path and said second path. A deployment-switching stop guides the shut-off panel along the second path when the shut-off panel is in contact with the deployment switching stop and the shaft is driven in a direction of rotation for deployment.
