As of January 2015, Tokyo Gas Co., Ltd., Toho Gas Co., Ltd., Saibu Gas Co., Ltd., Shizuoka Gas Co., Ltd., Keiyo Gas Co., Ltd., Osaka Gas Co., Ltd., Hokkaido Gas Co., Ltd. Hiroshima Gas Co., Ltd., Odawara Gas Co., Ltd., Oita Gas Co., Ltd., Okayama Gas Co., Ltd., Daiwa Gas, Tobu Gas, Yamaguchi Godo Gas, Tokai Gas, Shikoku Gas and the Gas Bureau of the City of Sendai have adopted the Panasonic household fuel cell (ENE FARM) and are promoting its installation and adoption in households. We have shipped a total of approx. 52,000 units.

Panasonic has developed a fuel cell unit with a built-in function for continuing to generate power during blackouts. Furthermore, to ensure flexible installation in various locations, we developed an integrated type whose backup boiler is built into the hot water storage unit, where the unit depth is maintained, in addition to the separate type where the backup boiler is separated from the hot water storage unit. Together with conventional household fuel cells for condominiums, we will expand product lineups to ensure flexibility for our customers' various installation conditions, and thereby further promote the spread of household fuel cells.

Household fuel cell for condominiums

Panasonic's 2015 household fuel cell (ENE FARM) models to be released in April 2015 maintain a 95.0% (LHV)*1 rated total efficiency, but the recommended price is approx. 300,000 yen* lower than FY2013 models by reconfiguring the power generating stack, simplifying the system and reducing the number of components (by approx.15%).
The fuel cell unit with a built-in function for continuing to generate power during blackouts does not require any additional device installation space or work. The price of the function for continuing to generate power during blackouts is approx. 60,000 yen* less than the separate optional device.

Household fuel cell for detached houses

In order to install household fuel cells in condominiums, we must meet additional requirements to those of detached houses. While maintaining the performance and ease of use of the 2013 model for detached houses, we have enabled fuel cell installation in the pipe shaft of open corridors *4 such as by improving the air tightness of the equipment main body.

In consideration of the limited installation space in condominiums, we improved quake resistance by increasing the strength of the leg sections that fix the equipment. To enable installation on upper floors, we ensured wind resistance to allow operations in strong winds by changing the supply/exhaust configuration. Our household fuel cells meet the installation standards for condominiums and can be installed, including the backup boiler, by being covered in the pipe shaft of condominiums.

Glossary

*1 (LHV): Lower heating value:
This denotes the value determined by subtracting latent heat of the water vapor from the amount of heat generated when the fuel gas is fully combusted. In contrast, HHV (higher heating value) includes the condensing latent heat of the vapor generated by combustion. City gas has an LHV/HHV ratio of approximately 0.903.

*2 Standard type model (other types of models may be available depending on gas companies)

*3 In the case of the model without a function for continuing to generate power during blackouts, the installation of a separate optional device enables the user to use the function.

*4  "Open corridors" refer to corridors in condominium and other buildings with dwellings on one side and the outside of the building on the other.
