Preserving the planet’s future with “solid” technologies

SOFC (Solid Oxide Fuel Cell) is a highly energy-efficient power generation system. A SOFC can generate energy by chemically reacting fuel (hydrogen) and oxygen, and also supply energy as heat. Kyocera has engaged in the development of miniaturized SOFC technologies since 1985, and we succeeded in installing our SOFC cell stack on the world's first residential SOFC in 2011.

BASIC STRUCTURE

Kyocera's SOFC cell stack uses several dozen ceramic power generation cells which are joined together in series. Each cell is a uniquely-designed cylindrical flat plate structure, and the resulting stack achieves excellent durability, miniaturization, and high power generation efficiency.

ADVANTAGES

  • High power generation efficiency
  • High durability/maintenance saving
  • Low noise
  • Recoverable heat energy

BASIC PERFORMANCE

Kyocera's SOFC cell stack has been improved since mass production started in 2011, and has achieved further miniaturization with the 3rd generation product. We have achieved approximately 90,000 hours of continuous operation and 360 operation cycles (*), equivalent of 12 years, by leveraging our advanced fine ceramics design, manufacturing, and evaluation technologies.
*Operated with 700℃ electric furnace and hydrogen/air conditions of electric generation. Results might differ based on the operating environment and conditions (temperature/gas content/etc.).

APPLICATIONS USAGE EXAMPLES

Kyocera's SOFC cell stacks have many uses in your daily life.

SOFCs are expected to be installed in communication base stations, traffic lights, and pipeline monitoring as backup power sources.

SOFCs are already widely used in households and small businesses such as convenience stores and restaurants.
