The global shift towards more efficient energy utilization and reduced environmental pollution has led to a surge in research and development of alternative energy sources, particularly in the automotive industry. While electric vehicles (EVs) have made a promising start, challenges like limited driving range and charging infrastructure persist. Fuel cell technology, especially Solid Oxide Fuel Cells (SOFCs), emerges as a potential solution due to their high energy efficiency, quick refilling times, and wide fuel compatibility. Unlike proton-exchange membrane (PEM) fuel cells that solely rely on hydrogen, SOFCs can operate on various fuels including biofuels like ethanol and ammonia. Studies have showcased the viability of SOFC vehicles in countries like Brazil, where biofuel infrastructure is prevalent, eliminating the need for constructing separate hydrogen infrastructure. The integration of SOFCs in vehicles has resulted in impressive drive ranges, with prototypes running on bio-ethanol achieving over 600 km. Additionally, SOFCs have been used as range extenders in electric vehicle models, showcasing significant improvements in drive ranges, reaching up to 823 km with certain fuel types. The reversible characteristic of SOFCs allows for energy regeneration, making them highly efficient and sustainable options for the transportation sector. While challenges like heat generation and integration complexities exist, the positive outlook on SOFCs in vehicles is evident in various studies and prototypes. The potential for SOFCs to revolutionize the automotive industry by offering cleaner, more efficient transportation solutions is promising, especially in regions where biofuels are widely available, showcasing a shift towards a more sustainable and practical approach in the realm of alternative energy for vehicles.
