  text: The propagation of single cell performance losses to adjacent cells in a polymer
    electrolyte fuel cell stack is studied by means of local current density measurements
    in a two cell stack. In this stack, the working conditions of adjacent cells can
    be controlled independently in order to deliberately change the performance of
    one cell (inducing cell) and study the coupling effects to the adjacent cell (response
    cell), while keeping the working conditions of the later one unchanged. The experiments
    have shown that changes in the current density distribution caused by lowering
    of the air stoichiometry in the inducing cell cause changes in the current density
    distribution of the response cell in the order of 60% of the change of the inducing
    cell, even when the air stoichiometry of the response cell is kept constant. The
    losses in cell voltage of the inducing cell cause losses in cell voltage of the
    response cell in a magnitude between 30 and 50%.
