Proton exchange membrane (PEM) fuel cells are promising devices to efficiently produce green electricity. However, one of the challenges hindering their commercialization is the waste heat management in which a great part of the outcoming energy is made of. For this matter, a great deal of emerging research is focused on heat recovery in PEM fuel cells. Thermoelectric generators are one of the technologies that have recently obtained notable attention for their potential for use as waste heat recovery in PEMFCs. Thermoelectric generators are solid state devices that directly convert the temperature gradient to electricity via the Seebeck effect.
In this review paper we will outline the current overview of the use of thermoelectric materials for the waste heat recovery especially in PEMFSc. Advantages and disadvantages of commonly used thermoelectric materials such as bismuth telluride and its alloys are discussed and the capability of alternative thermoelectric materials such as Skutterudite structures, Half-Heusler compounds, carbon nanotubes and their composites and thermoelectric oxides are scrutinized.
