The world’s smallest high-efficiency household fuel cell cogeneration system “ENE-FARM MINI” was jointly developed and commercialized.

Dainichi Kogyo Co., Ltd., Kyocera Co., Ltd. Tokyo Gas Co., Ltd. have jointly developed “Fuel Cell Unit with a Built-in hot water storage tank) called the ENE-FARM MINI”, the world’s smallest size household fuel cell cogeneration system.

The new ENE-FARM MINI system has now been commercialized and has been adopted by Tokyo Gas and will start selling the units starting on October 30, 2019.

The world’s smallest size, which is the same size as an outdoor air conditioner unit, has been achieved by reducing the size of the cell stack and hot water storage tank, which are the main components of the power generation system.

By satisfying the installation conditions, it can be installed in a 500mm depth space, so it can be used even in customer homes where the larger ENE-FARM units could not be installed.

Rated power output (400W) and energy-saving according to energy load

A solid oxide fuel cell (SOFC) with high power generation efficiency is used, and the rated power output is 400W. Expected to reduce annual CO₂ emissions by approximately 1 ton while at the same time realizing high energy savings.

Resilience function come standard

The ENE-FARM MINI will continue to generate power even if a power failure occurs. TVs and mobile phones can be charged from a dedicated outlet during a power failure, and hot water supply and floor heating can also be used.

The Chairman of DAINICHI Jijing said”After decades of co-development of fuel cells, the launch of the new product has finally been launched,” said DAINICHI Jijing, chairman of the press conference. This time the fuel cell unit will be supplied to Tokyo Gas Company under the brand of Kyocera, and a large number of pre-sale orders have been obtained since the beginning of the sale. In the future, fuel cell units will become the pillar products of DAINICHI. ”

Japan’s Ministry of Economy, Trade, and Industry has set a target of 5.3 million fixed fuel cells by 2030. “There is great potential for future development and hopes to contribute to the popularization of fuel cell units in Japan,” said the Chairman of Yoshii.
