Fuel Cell
A fuel cell transforms chemical reaction energy into electricity. There are different types but in the frame of this project the consortium concentrates on a solid oxide fuel cell (SOFC). Such a SOFC operates at temperatures between 650 and 1000°C.
There are two types to differentiate. One is constructed tubularly and the other planarly. In the project a planar SOFC is being developed.
All SOFCs are based on the same method: Redox-reactions between oxygen from air and compounds of the producer gas lead to a concentration gradient of oxygen between anode and cathode. The electrolyte between anode and cathode is permeable for oxygen-ions only and charge differences and current flow are the consequence.
Fuel cells are sensitive to impurities of the used gases. Sulphur compounds for instance have a highly deactivating effect. Therefore the right gas treatment is crucial for a longer lifespan of the cell.
