Ultra Pure Hydrogen From Biomass

A major problem in the modern world is the conflict between sustainability and cost-effective energy production. Various solutions have been proposed and developed in recent years, but few have been met with mainstream acceptance and commercialization, largely due to their prohibitive cost or low productivity.  One technology that has succeeded to a small degree but continues to grow is hydrogen fuel cells.  These emissionless, efficient, and safe systems are being implemented in a variety of applications, from transportation to industrial power.  However, current methods of obtaining hydrogen gas, the fuel they require, are not particularly sustainable and are often supported by the fossil fuels that the fuel cell systems seek to replace.
This technology works around that problem by synthesizing hydrogen gas from a very renewable resource, biomass.  Through a series of physical and chemical reactions, this system turns pellets of wood or other plant material into H2, in high enough purity to feed directly into a fuel cell.  This invention is a system for converting gasified biomass into pure hydrogen gas that can be used to power a fuel cell.  The system uses a steam generator to mix the syngas formed by the biomass with water vapor before forcing it into a water gas shift reactor.  The reactor mixes the steam and syngas, forces it through a charcoal layer and then reacts the gas with a catalyst.
