The flow field plate in a proton exchange membrane (PEM) fuel cell is a crucial part for the global performance leading to a big potential for optimization. The idea is to optimize the flow field plate and achieve an increase in efficiency of the fuel cell by applying the principle of uniform entropy production used in non-equilibrium thermodynamics. Literature shows that this can be achieved by using bio-inspired flow fields based on for instance human lungs or leaves. These bio-inspired flow patterns will be modelled and simulations will be conducted to find the most efficient flow field plates. The most promising designs will then be manufactured and tested against industrial used reference designs. This will be done in a newly built fuel cell test station to see if any improvements in the characteristic amperage-voltage curves can be found.
