Bipolar plates, or BPPs, are one of the most common components in fuel cell stacks. So, which BPP is put in a stack has a huge impact on functionality and costs. Three research projects, InProPlate, PreCoil and BePPel, funded by the German hydrogen and fuel cell program NIP II, have come up with new techniques that, above all, promise a significant reduction in manufacturing and measurement costs.
