Quoted from the paper presented at the Canadian Hydrogen conference. The title is "Development of a solid oxide fuel cell (SOFC) automotive auxiliary power unit (APU) fueled by gasoline".
There are 5 names of Delphi people and 6 names of GLE people.

The introduction includes the following:

Delphi has divided the system into several engineering teams and is currently working with GLE as the developer of the stack sub-system..........
Commercial challenges do exist for this product but are being identified and additional development programs have been initiated to address those challenges.

The paper identifies the sub-systems of SOFC APU
Thermal Management Enclosure
Fuel reformer
SOFC stack
Waste energy recovery unit
Process air supply
Control system and module
Power Electronics: 40 volt LiPo battery and DC-DC converter

There are paragraphs on the various subsystems but the bulk of the paper concentrates on the SOFC stack and the performance of the cells.

Development of SOFC stack:

Delphi is working with Global Thermoelectric in developing SOFC stacks that meet the stringent volume, weight and thermal cycling restrictions imposed by the auto industry.
The stacks have been sized for the auto voltage requirements (42V) and power outputs (3-5 kW). The stack configuration consists of 4 27-cell modules that are mounted on a gas delivery manifold/heat exchanger base. These modules are then electrically connected outside of the hot zone to achieve the 42V requirement.

Conclusion and Summary of Results:

This paper describes the development of a solid oxide fuel cell auxiliary power unit system focusing on stack development and system integration. The fuel cell team at Delphi is currently working on building a proof of concept unit to demonstrate the advantages of such an APU unit. Some of the concepts and progress is discussed in this paper. Delphi's development SOFC stack supplier, Global Thermoelectric, has made great progress in basic cell technology to meet some of the requirements of the automotive industry.

Currently(sic) and future development will be focused on:

. Reducing cost for commercialization
. Improving system power density
. Improving fuel utilization
. Achieving fast startup of system
. Achieving automotive levels of durability over usage and thermal cycles

The SOFC based APU technology has key advantages for the customer. It provides a paradigm shift in the supply of electric power to passenger cars. This is consistent with the increasing power demands in automobiles in the new era of more comfort and safety. Delphi and its partners are working towards developing a Solid Oxide-based system to answer these requirements.
