abstract = {The criterion for the applicability of any tomographic
method is its ability to construct the desired inner
structure of a system from external measurements, i.e. to
solve the inverse problem. Magnetotomography applied to fuel
cells and fuel cell stacks aims at determining the inner
current densities from measurements of the external magnetic
field. This is an interesting idea since in those systems
the inner electric current densities are large, several
hundred mA per cm(2) and therefore relatively high external
magnetic fields can be expected. Still the question remains
how uniquely the inverse problem can be solved. Here we
present a proof that by exploiting Maxwell's equations
extensively the inverse problem of magnetotomography becomes
unique under rather mild assumptions and we show that these
assumptions are fulfilled in fuel cells and fuel cell
stacks. Moreover, our proof holds true for any other device
fulfilling the assumptions listed here. Admittedly, our
proof has one caveat: it does not contain an estimate of the
precision requirements the measurements need to fulfil for
enabling reconstruction of the inner current densities from
external magnetic fields.},
