MCFC control system.

Design of a Control Unit of a 300 kV MCFC Cogeneration plant

Project Description

“Procyon” is a research project with the aim of developing a 300 kV stationary cogeneration plant employing high-temperature fuel cells fed by natural gas, which is built at Campus Palmas Altas, Abengoa‘s headquarters in Seville. Specifically, “Procyon” is based in molten carbonate fuel cells (MCFCs), which are high-temperature fuel cells that use an electrolyte composed of a molten carbonate salt mixture suspended in a porous, chemically inert ceramic matrix of beta-alumina solid electrolyte (BASE).

Since MCFCs operate at high temperatures of 650ºC and even above, non-precious metals can be used as catalysts at the anode and cathode, thus reducing costs.  Improved efficiency is another reason MCFCs offer significant cost reductions over other fuel cell technologies. Indeed, MCFCs can reach efficiencies approaching 60%, considerably higher than, for instance,  40% efficiency of a phosphoric acid fuel cell plant. Additionally, MCFCs are not prone to poisoning by carbon monoxide or carbon dioxide.

“Procyon” project is undertaken by Hynergreen,which is an Abengoa subsidiary aimed to organize and develop activities and projects connected with electricity production utilizing different technology fuel cells, as well as the production of hydrogen from renewable sources, and the clean and efficient thereof. “Procyon” has also been financially supported by Corporación Tecnológica de Andalucía (CTA).
