TMC, Aisin Provide Household Fuel Cells for Test Program
Tokyo—TOYOTA MOTOR CORPORATION (TMC) and AISIN
SEIKI CO., LTD. (Aisin) announce they will provide a total of 30
residential, solid-oxide fuel-cell (SOFC1) cogeneration
systems developed jointly by Osaka Gas Co., Ltd. (Osaka Gas), Kyocera
Corporation (Kyocera), TMC and Aisin to five Japanese gas companies, as
part of the New Energy and Industrial Technology Development
Organization's (NEDO's) Solid Oxide Fuel Cell Verification Project2 for 2009.
Specifically, TMC and Aisin will provide four SOFC cogeneration systems
to Tokyo Gas Co. Ltd., one to Toho Gas Co., Ltd., 23 to Osaka Gas and
one to Saibu Gas Co., Ltd. TMC and Aisin have already supplied one to
Hokkaido Gas Co., Ltd. Once installation is complete in regular
households, the five gas companies will gather data necessary for
commercialization.
TMC and Aisin have worked together with Osaka Gas and Kyocera since
March 2009 on the development of residential SOFC cogeneration systems.
By joining in this verification project to gather data for the
research and development of commercially viable systems, they hope to
accelerate progress, culminating in the commercialization of
residential SOFC cogeneration systems by the first half of the 2010s.
1Fuel cells using ceramic electrolytes.
Oxygen is ionized and, by passing through an electrolyte, chemically
reacts with hydrogen and carbon monoxide, generating electricity. One
of the notable characteristics of this system is that it uses carbon
monoxide.
2Begun in 2007; the project's aim is to install residential
SOFC cogeneration systems in regular households to identify future
technological development issues based on the data acquired. Unless
otherwise noted, years mentioned are from April 1 to March 31.

Features
1.
System is one third lighter and smaller than TMC and Aisin's 2008
system1, facilitating easier installation in
multi-unit housing complexes and detached houses.
2.
Modifications to cell2 electrodes have improved
durability.
