Solid oxide fuel cells: what challenges?

This data-file reviews fifty patents into solid oxide fuel cells, filed by leading companies in the space in 2020, in order to understand the key challenges the industry is striving to overcome.

The key focus areas are improving the longevity and efficiency of SOFCs. But unfortunately, we find many of the proposed solutions are likely to increase end costs.

Economics of SOFCs could eventually become very exciting for low-carbon heat and power (model here). But our conclusion from the latest patents is that the technology is not yet on the path to deflate and achieve cost competitiveness in the near-term.
