The work at VTT Fuel Cells and Hydrogen focuses primarily on the most common low temperature and high temperature FC&H2 technologies: proton exchange membrane fuel cells (PEMFC) and solid oxide technologies (SOFC and SOEC), respectively. PEMFCs are commonly utilized, e.g. as vehicle and back-up power sources, whereas the high-temperature SOFCs are better suited for large-scale stationary installations. Solid oxide electrolysis cells (SOECs) are a developing technology, which promises an ultimately efficient hydrogen production pathway. Integrating SOFCs and SOECs into a single device, then again, enables a completely carbon neutral, highly efficient large-scale electrical energy storage technology. With world class knowhow and constantly developing research facilities our team aims for wide range of partnerships hoping to serve both stack developers and balance-of-plant component developers as well as system integrators.
