      abstract     = {A novel scheme for detecting inhomogeneous internal
                      currents in a fuel cell stack is presented. In this paper
                      the scheme is investigated for the case that the flow field
                      plates consist of graphite. Then plates of high
                      conductivity, e.g. aluminium between the flow field plates
                      together with small slits in these plates have three
                      effects: (a) Whenever a local inhomogeneity of the electric
                      current occurs at a particular cell in the stack, this will
                      induce a surface current close to that cell perpendicular to
                      the averaged current. This current can be detected. (b) The
                      plates of high conductivity completely prevent the
                      inhomogeneities from spreading to neighbouring cells. (c)
                      Even at the particular cell the inhomogeneity is suppressed
                      as far as possible. Thus this scheme leads to much better
                      diagnostic possibilities and at the same time reduces
                      electric instabilities to an extent, where they probably
                      become harmless. This scheme will first be explained for a
                      simple model to clarify the idea. However, very precise
                      three dimensional computations using realistic parameters
                      are presented, corroborating the results of the simple
                      model. Copyright (C) 2009 John Wiley $\&$ Sons, Ltd.},
