  • Method for reusing current collectors/distributors of solid polymer electrolyte fuel cell stacks
    Patent number: 7294428
    Abstract: The method for reusing current collectors/distributors is employed in an electrochemical generator (1, 20) comprising a multiplicity of elementary cells (2, 21) assembled in a filter-press configuration and comprising an array of conductive sheets (3) and of current collectors/distributors (7, 22). The method of the invention provides dissembling the electrochemical generator (1) once the presence of a damaged elementary cell (2, 21) is detected. Subsequently, the method of the invention provides repairing/replacing the damaged cell for later reassembling the electrochemical generator (1, 20) reusing the original current collectors/distributors (7, 22). to achieve this, while reassembling the electrochemical generator (1, 20), a mechanical means for adapting (8, 12, 13, 14, 15) is inserted between each conducting sheet (3) and the respective current collector/distributor (7, 21).
