Desulfurizer-Reformer Reactor System for use with Solid Oxide Fuel Cells


Project ID:  D2008-25



Fuel cells are electrochemical devices that continuously convert chemical energy into electric energy for as long as fuel and oxidant are supplied. The primary advantages of fuel cell power generation include increased efficiency, lower weight, smaller size, less air pollution, and reduced noise. However, diesel fuel is invariably sulfur-laden and when sulfur is present in any fuel that is used in a fuel cell, it poisons the fuel cell anode and reforming catalyst.


Invention Description:

Novel method of developing robust sulfur-tolerant reforming catalyst and agile sulfur sorbent formulations for logistic fuels including diesel, coal and, jet and aviation fuels.



·       Two-in-one design for simultaneous desulfurization and reforming at the same temperature

·       Produces clean, sulfur-free, hydrogen-rich ready-to use SOFC feed from logistic fuels for the fuel cells in a single reactor system

·       Compact and efficient three-chamber design for more effective thermal management

·       Thermally and microstructurally stable

·       Sulfur-active at high temperatures

·       Does not need regeneration

·       Simple, cost-effective disposal method—able to treat as solid waste

·       Formulation of two kinds of sulfur-tolerant catalyst support

·       Novel and effective route for nanoporous matrix (NM) incorporation

·       Enhances performance via metal oxide additives:

·       Departure from currently used designs of: (i) packed- or fluidized-bed and (ii) coated corrugated foil (Catacel).

o   Obviates large pressure drops

o   Enhances exposure area (both sides active)



·       Produces ready-to-use Solid Oxide Fuel Cell (SOFC) feed
