NOVELTY - An electrochemical cell apparatus has an electrochemical cell electrically conductive support (10) comprising a conductive core. The conductive core comprises an active area which is covered with an electrically and thermally conductive polymeric composite (12).    USE - For electrochemical cell.    ADVANTAGE - The conductive support has excellent chemical resistance, resistance to hydrolysis, good mechanical integrity, roughness and good conductivity. The conductive support has a volume resistivity of 0.5 OMEGA cm or less, preferably 0.045 OMEGA cm or less and thermal conductivity of at least 5 watts/m K, preferably at least 13 watts/m K. The conductive support is produced economically from inexpensive raw materials. The connectors support allows the heat generated by the electrochemical cell to be laterally conducted and transferred to circulating fluids such as air, thus the complexity of the support and its manufacture are reduced. The use of thin layer of adhesion promoter between the core and the polymeric composite reduces the tendency of the core and polymeric composite to debond and disparity in the dimensional stability of the core and polymer composite, without decreasing electrical and thermal conductivity.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) A system, which has conductive support, a gas supply unit for supplying fuel gases and oxidant gases to the fuel cell membranes, electrical unit for transporting electrical charge to and from the fuel cell membranes, electrical unit for conditioning power produced by fuel cell membranes, and control unit for controlling the fuel gases, oxidant gases and electrical unit; and    (2) An electrochemical cell component which has a conductive core, and an electrically and thermally conductive polymer composite covering and adhered to core by an adhesion promoter. The electrochemical cell component has a volume resistivity of 0.116 OMEGA cm or less.
