Abstract (en)
[origin: WO2022101569A1] The invention relates to a clamping device (400) for an electrochemical stack (200), said device comprising: an upper clamping plate (410) and a lower clamping plate (420), each facing the other by a lower inner face (420b) and an upper inner face (420a) thereof, respectively; a unitary spring member (500) that has an axis of revolution XX' and consists of an assembly, at a hub (503), of two spring washers (501, 502) of generally frusto-conical shape, said spring member (500) being configured to clamp the two clamping plates against the electrochemical stack (200) clamped between said clamping plates, the spring member incorporating a fluid circuit formed in the volume of both of the two spring washers; and a retaining means (600) for maintaining the clamping force applied by the spring member to the clamping plates.
