Excess Heat

In this paper, the concept of an SOFC (Solid Oxide Fuel Cell) and PEFC (Polymer Electrolyte Fuel Cell) hybrid system is presented. Large-scale SOFC systems operated in a thermally self-sustainable state produce excess heat. The excess heat can be used for producing hydrogen. Several variations of hydrogen production systems are presented here. One way is to produce the hydrogen by using an extra reformer. Another way is purifying the off-fuel of SOFCs. The produced hydrogen can be used as the fuel for PEFCs. The overall electrical efficiency of a combination of an SOFC and PEFCs is higher than that of a standalone SOFC. When the hydrogen produced by purifying the off-fuel of the SOFC is used as the fuel for PEFCs, the overall electrical conversion efficiency increases by around 20%.
