FUEL CELLS
Delphi Solid Oxide Fuel Cell Stack
Delphi's Solid Oxide Fuel Cell (SOFC) technology is commercially
ready for a wide range of high volume stationary power generation
and transportation industry applications. Delphi's innovative fuel cell
is robust, fuel flexible and highly efficient. A single Delphi Gen 4
SOFC Stack can provide 9 kW of electrical power and it features a
modular design, ideal for integration into large power plants.
Delphi has developed two stack sizes which can be implemented
into a stationary or transportation application. They provide
increased efficiency and reliability while decreasing emissions when
compared to conventional technology. Delphi's low cost solid oxide
fuel cell stacks are designed for high volume manufacturing.
Processes are developed and critical suppliers have been identified
for all components.
Delphi Solid Oxide Fuel Cell Stack
Delphi's fuel cell technology can operate with natural gas, hydrogen, gasoline, diesel fuel, bio fuels, or other
hydrocarbon fuels. The fuel is converted directly to electrical energy without thermal-mechanical conversion.
Therefore, potential efficiency is not limited by the Carnot Cycle and the fuel cell can achieve higher efficiency than
internal combustion engines and other conventional power sources. Additional benefits to the fuel cell technology
are the reduction in operating noise and a low level of emissions.

Performance Advantages
Delphi's Solid Oxide Fuel Cell technology can produce electricity with a wide range of fuels including
natural gas, hydrogen, gasoline, diesel, bio fuel, or other hydrocarbon fuels. Its efficiency has been
demonstrated to be higher than other fuel cell technologies in stationary applications, including: phosphoric
acid, molten carbonate, and polymer electrolyte designs. Delphi's SOFC technology also offers advantages
in overall performance, material cost, and reliability compared with competitive fuel cell technologies.
Delphi's SOFC Stack designs feature laser welded cassette repeating unit configuration for excellent
durability. Their coated stainless steel castings, stamped metallic cassette components, and glass-ceramic
seals provide durability and low cost.
