Tohoku University Technology: Solid oxide fuel cell able to miniaturize : T08-142
Lamination technology that enables high electric power density without compromising power generation efficiency
Fuel cells are attracting attention as an environmentally friendly energy, and various forms are being researched and developed. Solid oxide fuel cells are focused from the energy efficiency perspective. For a solid oxide fuel cell containing multi-cells, fuel and air are supplied separately from the same direction to the anode and cathode of each cell, which requires a fuel and an air supply unit, respectively. In addition, since the solid oxide fuel cells have a structure in which a solid electrolyte is sandwiched between an anode and a cathode, the fuel and air supply system becomes complicated in order to supply them separately to the anode and cathode which are close to each other. This is the reason why the full cell miniaturization was difficult. This invention is based on the structure of the electrode layer. By separating the fuel and air input & output respectively, a smooth flow can be achieved and the power generation efficiency can be improved.

Company information
The revenue generated from technology transfer is reinvested as new research funding for universities and researchers, and is utilized to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will vigorously promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by signing basic technology transfer agreements with the following universities (as of June 1, 2025): Tohoku University, Hirosaki University, Iwate University, Akita University, Fukushima University, Yamagata University, Tohoku Gakuin University, Iwate Medical University, Fukushima Medical University, Aizu University, Miyagi University, Hokkaido University, Muroran Institute of Technology, and Showa Medical University.
