- NGK SPARK PLUG and Mitsubishi Hitachi Power Systems Establish Joint Venture CECYLLS Co., Ltd.
TOKYO— NGK SPARK PLUG CO., LTD. (NTK) and Mitsubishi Hitachi Power Systems, Ltd. (MHPS) today announced the establishment of CECYLLS Co., Ltd., a joint venture company on January 29.
The two companies had concluded an agreement in July 2019 to establish the joint venture to manufacture and sell cylindrical cell stacks(1) as the power generating elements used in solid oxide fuel cells (SOFC)(2).
MHPS’ SOFC is the latest in technology to utilize clean hydrogen as a fuel source. The new company will utilize NTK’s mass production technologies of ceramics to produce and sell MHPS’ cylindrical cell stacks that feature long-life and efficient heat utilization capabilities.
(1) Cylindrical fuel stacks are structures of elements (a laminate of fuel electrodes, electrolytes, and air electrodes) on the outer surface of a high-strength ceramic substrate tube, which produces a power-generating reaction. The elements are serially connected by a conductive ceramic interconnector (cylindrical horizontal-stripe cell stack), allowing for efficient generation of low current, high voltage electricity.
(2) Solid oxide fuel cells (SOFC) generate electricity using oxygen (O2) from the air, along with hydrogen (H2) and carbon monoxide (CO) extracted from reformed town gas or other sources. The cell stacks that are the core component for power generation are composed entirely of ceramic.
