Viking House, Foundry Lane, RH13 5PX Horsham/UK Contact authors: www.EFCF.com/ContactRequest Abstract Ceres continues to acquire commercial partners for its low-temperature metal supported SOFC technology (the ‘Steel Cell®’) based predominantly around the use of ceria. This unique design architecture allows for a robust, low cost, subsidy free fuel cell product, whilst retaining the advantages of fuel flexibility, high efficiency and low degradation. Over the last year, several significant technological and commercial developments have taken place. The latest version 5 iteration of the core SteelCell® technology has completed verification and has been released to customers. This technology iteration offers higher power, the ability to operate at higher fuel utilization/efficiency and state-of-the-art performance degradation rates, whilst retaining the outstanding robustness to thermal cycling, vibration and REDOX cycling characteristic of SteelCell technology. Major commercial developments include the commercial launch of a 4.2kWe light commercial CHP system with Miura in Japan, and ongoing strategic collaboration agreements with both Robert Bosch in Germany, primarily for manufacturing, and Weichai Power in China, for on-vehicle applications. In addition, a new collaboration and license agreement has been signed with Doosan in South Korea to jointly develop 5-20kWe low- carbon power generation systems. Ceres now has active commercial programs at 1kWe, 5kWe, 10kWe and 10’s of kWe and for that reason Ceres has developed an innovative 5kWe class stack design which can be used in an array to achieve higher power outputs. Development programs are ongoing with OEM’s with global reach based in Japan, North America and Europe. To meet the rapidly increasing demand for cells for customer programs, Ceres has invested in a larger manufacturing site near Redhill, UK capable of manufacturing >2MW/y initially with space for significant expansion. Despite the considerable challenges caused by the coronavirus pandemic, production has been rapidly ramped up at the new Redhill site during 2020 with investment released for further expansion of production capacity in the UK. Significantly, our first manufacturing licensee has successfully commenced pilot production in Bamberg, Germany, under ISO9001. Product Development of a 1kW μCHP Hydrogen-only System Reference Design has demonstrated a 40% system level cost reduction compared to NG systems at 1kW scale at equivalent efficiency. A further development has been the evaluation of SteelCell® technology for steam electrolysis applications, promising initial results of which are reported in this paper.
