Non-conventional fuel cell systems: New concepts and development

The increasing need for new energy conversion technologies that are compatible to strict environmental requirements has made fuel cells one of the most extensive and active research developments of materials and systems. However, current solid-state fuel cell technology such as solid state fuel cells (SOFC) or solid polymer fuel cells has met a number of problems concerning materials and technology. The so-called non-conventional systems provide new routes to avoid the problems associated with the high temperature SOFC plants.
