Graphite foil has been considered as a promising bipolar plate material in polymer electrolyte fuel cells due to its high electrical conductance and high corrosion resistance as well as low manufacturing costs. However, the highly flexible character of graphite foil led to physical deformation under external mechanical and thermal stimuli during fu...
