ABSTRACT
The polymer electrolyte membrane (PEM) fuel cell is a promising
candidate as zero-emission power source for transport and stationary
cogeneration applications due to its high efficiency, low-temperature
operation, high power density, and converting fuel to water as the only
by product. Bipolar plate is a backbone component of PEM fuel cells,
which supplies fuel and oxidant to reactive sites, removes reaction
products, collects produced current and provides mechanical support for
the cells in the stack. Bipolar plates constitute more than 80 % of the
weight and 45% of the total cost in a fuel cell stack. For this reason,
the weight, volume and cost of the fuel cell stack can be reduced
significantly by improving fabrication process and using lightweight
materials. Different fabrication techniques had been developed for these
plates to achieve optimally functions efficiently, with the aim of
obtaining high performance and economic advantages.
