The LivingH2 project is carried out from 01.10.2020 to 30.09.2022. It develops an improved fuel cell based CHP system with a new catalytic burner that works as the FC off-gas burner and as peak load burner as well as an improved PEMFC MEAs (membrane electrode assemblies) to improve stability and lifetime for pure hydrogen operation. It also validates a complete setup of a pure and renewable hydrogen CHP in a real but controlled environment to provide heat and power to a building.
