      abstract     = {In this paper, a new, simple method for measuring the
                      current density distribution in fuel cells with meander flow
                      fields is described. This method has been used to
                      investigate the reactant activity along the meander channel.
                      The corresponding experimental hardware is very simple,
                      cost-effective and easy to integrate into the fuel cells. A
                      thin semi-segmented plate made of expanded graphite serves
                      as a passive resistor network. The set-up is based on the
                      idea that the electronic conductivity of the expanded
                      graphite is relatively low in current direction. For typical
                      current densities in polymer electrolyte fuel cell (PEFC),
                      this leads to voltage drops in the range of several
                      millivolts using usual current densities. On the other hand,
                      the conductivity in-plane is considerable higher which is
                      beneficial for equalizing the potential across the segment
                      area. The new set-up can be used to measure the current
                      density distribution in a single cell as well as in a stack
                      at any desired position. The local potential difference
                      across the graphite plate is caused by the local current
                      flowing through it. By mapping these potential differences
                      at different locations, the current distribution in the fuel
                      cell can be derived. This experimental set-up has been used
                      to investigate the current distribution of a 240 cm(2) PEFC
                      single cell with different operating conditions. The
                      real-time current density distributions measured by the
                      present method are described in this paper. (c) 2005
