Tokyo Gas Co Ltd and Kyocera Corp announced the "Ene-Farm Mini," a compact residential fuel-cell co-generation system for apartment and condominium buildings, Oct 10, 2019.
For the Ene-Farm Mini, which will be released Oct 30, 2019, a solid oxide fuel cell (SOFC) having a relatively high power generation efficiency was employed.
The size of the fuel-cell unit is equivalent to that of the outdoor unit of an air conditioner and the smallest in the world, according to the companies. With the small size, they aim to target the fuel-cell co-generation system not only at detached houses but also at multi-family apartment buildings.
By tapping the apartment/condominium market, which has a large size, Tokyo Gas and Kyocera expect to increase unit sales.
As of the end of July 2019, Tokyo Gas had sold 120,000 fuel-cell co-generation systems in total. It has a goal of selling 18,000 units per year. With the new product designed for multi-family apartment buildings, the company aims to tap the new market to further increase unit sales.
When a certain level of output is ensure for a fuel-cell co-generation system, the sizes of its components increase. On the other hand, the fuel-cell unit (whose size cannot be easily reduced) of the new product measures only 800 x 700 x 350mm.
As a result, the new fuel-cell co-generation system can be set up in places with a depth of only 500mm and, therefore, in multi-family apartment buildings.
