Fuel Catalyst improves the combustibility of hydrocarbon fuels by treating the fuel immediately before it enters the combustion chamber. This process removes carbon build up and prevents it from re forming. The improved combustion also reduces contamination entering the engine oil and other engine areas, resulting in longer engine life. The catalyst acts on impurity molecules in fuel converting them into extremely active small molecules which have the effect of cracking.

Fuel cell blowers are required to move fuels, gases and byproduct condensate throughout the system. Since it draw power from the system, it plays a key factor in overall efficiency. A high efficiency blower has a lower parasitic load on the system and may allow for a reduced fuel cell stack and lower power invertors costs. While choosing the blower we have to check for its reliability and the spark free operation.

Fuel cells require alternating heating and cooling for optimum performance. A liquid circulation loop is provided with water or glycolic solution and is regulated by a heating unit and heat exchanger to maintain the stack at the desired temperature. Fuel cell stack coolant water is processed by moving the two-phase water/steam coolant exhaust through a steam separator wherein the water phase is separated from the steam phase. The water phase is then moved through a heat exchanger where its temperature is lowered to a subcooled level which is below the coolant operating temperature in the stack. A flow control valve is associated with the coolant heat exchanger to regulate water flow through and/or around the heat exchanger depending on the temperature of the water which leaves the steam separator. By subcooling the coolant before it reenters the stack, a lessening of electrolyte loss through evaporation is achieved.

Fuel check valve is used to prevent fuel leakage from vehicle. The valve is connected in the fuel vapor line between canisters and overfills limiter. It contains two balls. Under normal conditions, the gasoline vapor passage in the valve is open. When vehicle roll over occurs, one of the balls closes the fuel passage thus preventing fuel leaks.

Fuel conditioners are made available to consumer outlets through service stations, discount stores, and automotive supply houses. These conditioners have been advertised to improve the overall performance of internal-combustion engines in a variety of ways with the end result that engine emissions are reduced. It is designed for interposition between an engine's fuel supply line and the engine's fuel combustion zone, which has a cylindrical body portion, with an input end and an output end. It consists of a metallic housing containing a plurality of reactive anti-biological elements and a high Gauss magnet. The fuel passes over the anti-biological elements and adjacent the magnet such that growth of biological agents entrained within the fuels is inhibited.

A fuel consumption control is a system for controlling and reducing the consumption of fuel by gas-fired cooking machines. The control system includes means for providing a sufficiently high rate of flow of gas to the cooking machine to permit proper cooking and a timer to maintain the high rate of gas consumption during the time the food products are in the cooking zone and, means for reducing the consumption of gas after the food products have exited from the cooking zone.
