In this proposed hybrid system, the SOFC
should be operated under controlled steady-state condition while the UC is providing the demanded power .
In addition to the model in reference (GELEN; YALCINOZ, 2013), the modified SOFC
model used in this paper includes a limiting module for the fuel utilization factor ([U.
25 April 2014 - US solid oxide fuel cell (SOFC
) components and systems maker WATT Fuel Cell Corp said it had bought local SOFC
developer Pittsburgh Electric Engines Inc (PEEI), without revealing financial details.
systems operating on coal syngas, natural gas or biogas can generate clean power with virtually zero pollutants and significant reductions in greenhouse gas emissions, particularly when configured for combined heat and power.
In the pressurized hybrid system, air pressurized by the MGT's compressor is supplied to SOFCs
and used as oxidant; then the thermal energy and pressure of the high-temperature exhaust gas from the SOFC
module are transferred to the MGT to be used, together with the unreacted portion of the gas, to produce electricity.
The program will focus on advancing 500 Watt to 1,000 Watt SOFC
power systems that operate on high-performance liquid fuels, including alternative bio-derived fuels such as butanol and bio-diesel.
Delphi and Peterbilt recently demonstrated an SOFC
APU installed in a Peterbilt Model 386 truck.
systems offer the opportunity to meet energy needs by producing electricity cleanly and quietly.
designs can use the electrolyte, the cathode, or the anode to provide structural support for the cell and various cell geometries such as tubular and planar.
Siemens Power Generation carried out the tests on the SOFC
, which is currently under development by the US Department of Energy's Solid State Energy Conversion Alliance.
The two companies have been collaborating on SOFC
technologies since 2003, but the new company will trade as an independent supplier of modules (or 'stacks', as they are known) and make its prototypes available both to Webasto and other system developers.
NanoDynamics says that most SOFC
systems are designed for much larger applications such as auxiliary power units.
