DENSO Corporation today announced that it has signed a manufacturing license agreement with Ceres Power Holdings (CWR.L), a leading developer of solid oxide cell stack technology. DENSO aims to advance the early practical application of Solid Oxide Electrolysis Cells (SOECs)*1 that produce hydrogen through water electrolysis.

Cell stacks are one of the components of SOECs, playing a role in separating steam into hydrogen and oxygen. Ceres has unique solid oxide technology joining metal and ceramic that leads to high-output performance. DENSO aims to realize mass production of high-quality cell stacks by utilizing Ceres’ technology with the company’s expertise of ceramic technology it has built in the automotive field, and to achieve the early practical application of SOECs with the company’s system technology including thermal management, system control and so forth.
