| Sumario: | <p id="p1">High-temperature thermoelectric generators (TEGs) have emerged as a key technology for improving fuel efficiency by recovering waste heat from automotive exhaust systems. While half-Heusler alloys are commonly used due to their excellent thermoelectric properties and mechanical stability, their susceptibility to oxidation and high production costs pose challenges for long-term application. In contrast, ceramic-based thermoelectric materials, including cobalt oxides, perovskites, and doped zinc oxides, offer superior high-temperature stability, oxidation resistance, and environmental compatibility. This chapter explores the potential of ceramic thermoelectric materials as viable replacements for half-Heusler alloys in automotive TEGs, assessing their performance, stability, fabrication challenges, and integration strategies. Furthermore, it highlights recent research advancements, material enhancements, and future prospects for optimizing ceramic-based TEG efficiency in automotive applications.</p> |
