abstract = {A novel tomographic scheme for analysing the state of any
single membrane electrode assembly (MEA) in a stack is
suggested. Plates of very high conductivity placed between
every fuel cell and slitted in an appropriate manner cause
surface currents at well-defined locations of the stack. We
show that knowing these surface currents, information about
anomalies of the currents in a MEA can be obtained using the
methods of tomography. The results are mathematically not
unique. However, when assuming plausible defect structures,
one can exclude improbable deficiencies by applying a
special form of simulated annealing. We present numerical
calculations of typical examples demonstrating that the
essential defects of the MEA in any single cell of the stack
can be detected and their extent can be determined.
