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.
Intelligent power networks and smart grid systems are demanding increasingly decentralized technologies that combine the storage and conversion of energy. Before this backdrop, in the scope of the EU’s CISTEM project (Construction of Improved HT-PEM MEAs and Stacks for Long Term Stable Modular CHP Units), a combined heat and power technology (CHP) has been developed on the basis of high temperature polymer electrolyte membrane fuel cells (HT-PEM FCs), which is able to provide an electrical output of up to 100 kWel. In addition to electricity generation, the heat produced by the HT-PEM fuel cell is used locally (more…)
