Abstract: A hydrogen and oxygen (HHO) gas on-demand electrolysis fuel cell system for use with internal combustion engines is disclosed. This hydrogen on-demand (HOD) system integrates with the engine control module (ECM) or other control system that regulates the operation of an internal combustion engine in order to supply HHO to the engine and improve the engine's overall fuel efficiency. This system includes an electrolyte fluid reservoir outfitted with level, pressure and temperature sensors; a pump and heat exchanger; a uniquely-configured electrolyzer; and a filter. The combined engine and HOD system is controlled and regulated by an electronic control system (ECS) and a combustion control module (CCM). The CCM is installed on the engine such that it actively intercepts the electronic signals from the engine manufacturer's ECM to continuously coordinate the functions and operations of the HOD system and the engine.

Abstract: A filter structure and method of filtration is disclosed for use in an electrolysis fuel cell system that is designed to produce hydrogen and oxygen (HHO) gas on-demand and to supply these gasses into the combustion chambers of internal combustion engines. The filter separates residual fluids and byproducts from HHO gas that is generated by the hydrogen on demand system, and is designed to be utilized with an electrolyte fluid reservoir; a pump and heat exchanger; and a uniquely-configured electrolyzer. The filter structure is multi-stage, and the disclosed method involves porting the HHO gas and byproducts through each filter stage separately to accomplish improved filtration.
