Decades of research on fuel cells have demonstrated their reliability as well as their ecological benefits. However, today's most widely used technology (PEMFC - Proton Exchange Membrane Fuel Cell) need extremely pure and thus expensive hydrogen to run. Systems capables of using various hydrogen sources, like the one that can be extracted from natural or bio-gaz, are currently being developed. Those systems (High Temperature PEMFC) run at a higher temperature that can be recovered to increase the overall efficiency (up to 95%) of the system. As of today though, there is no material able to withstand the harsh conditions of the HT-PEMFC. HYCCO is a French startup currently tackling this challenge and we already managed to produce break through fuel cell bipolar plates that are thinner, lighter and resilient than any other materials. Those ultra-light and durable components can be used for both LT-PEMFC and HT-PEMFC.
