Solid Oxide Fuel Cells Operating on Alternative and Renewable Fuels
Performer: Pennsylvania State University
Project No: NT0004396
Pennsylvania State University (PSU) will develop fuel processors for anaerobic digester gas (ADG) and commercial diesel fuels. These fuel processors will transform ADG and diesel fuel into syngas fuel, which can be utilized in solid-oxide fuel cells (SOFCs). The trace contaminants present in the ADG and diesel-derived syngas fuel are expected to overlap coal syngas contaminants with respect to level and variety of contaminants. Therefore this work will also include the development of adsorbents suitable for trace contaminant removal. Data from the operation of SOFCs on reformed diesel fuel will be applicable to early market SOFC spin-off applications, e.g., truck auxiliary power units (APUs).
The major work of this project is focused on the 1) preparation and evaluation of novel sorbents including molecular basket sorbent (MBS) and mixed metal oxides adsorbents for ADG cleanup; 2) improvement of the adsorption performance of mesoporous molecular sieve supported nickel (Ni) adsorbents and mixed Titanium-Cerium-Oxygen (Ti-Ce-O) based adsorbents for adsorptive desulfurization of ULSD; 3) evaluation and characterization of Ni-based catalysts for steam reforming of commercial diesel fuel; and 4) the testing of SOFC stack delivered to PSU by Delphi, and 5) the continued operation of a Ni-yttria-stabilized zirconia (YSZ) single cell SOFC on both a model ADG and also a commercial diesel reformate.
