Development is being made to expand the application range of the SOFC (solid oxide fuel cell). The aim of the development is to apply the SOFCs to the power sources of, for example, small electronics devices such as laptops and mobile phones by lowering the operating temperature of the SOFCs, which operate at high temperatures of 700 to 1000°C.
Recently, I wrote three new electrolyte materials for use with the SOFC operating at temperatures from 350 to 600°C.
Meanwhile, at the same time, SiEnergy Systems, LLC(USA)announced the success in prototyping a micro SOFC operating at 500°C or lower, and revealed an innovative process for fabricating the electrolyte film used by the micro SOFC. The fabricating process is capable of scaling up an active area of the electrolyte film to arbitrary dimensions depending on total power needed.
SiEnergy Systems is one of the subsidiaries of Allied Minds (U.S. private equity company).
