An electrochemical cell (3) for use in a fuel cell stack (1) comprising a resilient electrical conduction member sub-assembly (10, 16) having a first flow plate (5, 9), a second flow plate (6, 8) and a bipolar plate (11, 22). A fluid chamber (17, 19) is created by the first flow plate (5, 9), the second flow plate (6, 8), the bipolar plate (11, 22) and an electrode (13, 18) and has an inflow duct (59, 63) and an outflow duct (61, 65). A resilient electrical conduction member (15, 20) is located within the fluid chamber (17, 19) so that in use, a fluid can flow between the inflow duct (59, 61) and the outflow duct (61, 65). The resilient electrical conduction member (15, 20) is in electrically conductive contact with the bipolar plate (11, 22) and with the electrode (13, 18) via a plurality of electrical contacts (51) and the resilient electrical conduction member (15, 20) is compressed between the bipolar plate (11, 22) and the electrode (13, 18).
