The latest report from IDTechEx delves into the emerging landscape of stationary fuel cells, highlighting the competition among proton exchange membrane (PEM), solid oxide fuel cells (SOFC), and alternative technologies like alkaline fuel cells (AFCs) and molten carbonate fuel cells (MCFCs). The report forecasts a significant market growth for alternative fuel cell technologies, with over 10% annual demand expected by 2035, totaling a market share of over US$676 million. High temperature fuel cells, particularly MCFCs, are positioned as strong competitors to SOFCs due to their efficiency in continuous power generation and potential applications in carbon capture alongside power generation. On the other hand, low temperature alternatives such as AFCs and phosphoric acid fuel cells (PAFCs) offer quick response times and high efficiencies, with AFCs emerging as a durable and efficient back-up power option. Despite the broader trend of manufacturers transitioning to PEMFCs or SOFCs, AFCs remain relevant as a cost-effective solution, especially for specific use cases. Direct methanol fuel cells (DMFCs) are noted for their low temperature operation using widely available methanol fuel, catering to niche applications. The market analysis concludes that the combined demand for MCFCs, PAFCs, AFCs, and DMFCs is expected to reach 750 MW annually by 2035. This comprehensive assessment by IDTechEx offers valuable insights into the evolving landscape of stationary fuel cell technologies and market dynamics.
