abstract = {A liquid (heat transfer oil) cooling system for high
temperature polymer electrolyte fuel cell (HT-PEFC) stacks
in the power range above 1 kWel using encapsulated cooling
cells was designed. Calculations showed that it is
sufficient to cool every third cell to maintain an operating
temperature of about 160 °C. An HT-PEFC stack module
including 12 cells with an active area of 320 cm2 each was
assembled and tested experimentally regarding the
temperature distribution from cell to cell. It was found
that sufficient cooling with an oil inlet temperature of 160
°C is guaranteed up to a current density of 450 mA/cm2 when
operated with synthetic reformate $(42\%$ H2, $57\%$ N2,
$1\%$ CO). At this current density, the maximum temperature
difference from cell to cell does not exceed 8.3 K.
Additionally, this cooling system provided enhanced
protection against leaks.},
