A Heusler alloy, Fe2VAl, is a promising candidate for thermoelectric power generation because of its high thermoelectric power factor, such as 5.5 mW/mK2at 300 K. This high power factor is produced by a steep pseudogap around the Fermi level. The simultaneous enhancement of Seebeck coefficient and electrical conductivity can be achieved by the control of valence electron concentration within a rigid band model. Moreover, recent studies in the off-stoichiometric composition control, such as Fe2-xV1+xAl, suggest that the modification of the electronic band structure can further enhance the Seebeck coefficient, resulting in the higher power factor. The power generation ability was evaluated by the construction of a thermoelectric module consisting of only the Fe2VAl alloy. A high output power density of 0.7 W/cm2 was then obtained. The durability of the Fe2VAl module derived from high mechanical strength and excellent resistance to oxidation enhances utility for practical thermoelectric power generation.
