Latest Patents
One of his latest patents is the "Anode Protection System for Shutdown of Solid Oxide Fuel Cell System." This invention includes a Reductant Supply and safety subsystem designed to prevent the re-oxidation of nickel in the anode layer during the shutdown of the solid oxide fuel cell (SOFC) stack. The system utilizes a reducing gas or vapor generated from ammonia or hydrogen-based materials stored in a portable container. Additionally, the SOFC anode protection subsystem maintains an internal pressure of 0.2 to 10 kPa to prevent air from entering the SOFC system. The Post Combustion and slip stream control subsystem features a catalyst converter that treats any residual reducing gas exiting from the SOFC stack.
Another notable patent is the "Method and Apparatus for Rapid Exhaust Catalyst Light-Off." This invention involves supplying an internal combustion engine with reformate from a hydrocarbon reformer during start-up and warm-up. The reformate fuel mixture is initially fuel-lean to ensure complete combustion while the exhaust converter is not yet functional. Shortly after start-up, the mixture transitions to fuel-rich, allowing unburned reformate fuel in the exhaust stream to ignite and rapidly heat the converter. This innovative approach delays gasoline or diesel fueling until both the engine and converter reach optimal operating temperatures.
