A beta-type Stirling machine capable of operating in a refrigeration mode. The Stirling machine has a cold section and a hot section, a displacement piston having a friction zone, and an engine piston having a friction zone. The Stirling machine has a single liner arranged in the hot section of the Stirling machine operating in the refrigeration mode, wherein the friction zones of the displacement piston and the engine piston slide within the single liner.

Beta-type Stirling machine

The invention relates to a cooling system for a fuel cell (), comprising a main heat-transfer-fluid circuit including a main circulation pump () and a heat exchanger () with the exterior, which feed an upstream pipe () supplying the fluid to the cells () of the fuel cell, said fluid leaving the cells via a downstream pipe () in order to return to the main pump. The system is characterised in that a secondary circuit, comprising a secondary circulation device () that circulates the fluid in an alternate manner, is connected in parallel with the main circuit to the upstream () and downstream () pipes and in that one or more controlled valves () allow the main circuit and the secondary circuit to operate independently.

The invention relates to a cooling system for a fuel cell, comprising a main heat-transfer-fluid circuit including a circulation pump () and a heat exchanger () with the exterior, which feed an upstream pipe () supplying the fluid to the cells () of the fuel cell, said fluid leaving the cells via a downstream pipe () in order to return to the main pump. The invention is characterized in that the main circuit comprises a three-port controlled valve () on each upstream () and downstream () pipe, the third available port () of the upstream pipe () being connected to the inlet of the pump () and the third available port () of the downstream pipe () being connected to the outlet of the pump in order to establish a secondary fluid circuit.
