The Oxycell process uses a combination of Fuel Cells and Oxygen-based combustion to produce Electrical Power, Mechanical Power and Hydrogen

• Process starts with a partial oxydisation of Hydrocarbon feedstock using oxygen + steam (as widely used in Gas industry = Steam reforming). This produces heat and Hydrogen plus Carbon Monoxide/ dioxide
• Combustion is tuned to produce optimum temperature for downstream SOFC.

• The Majority of the produced Hydrogen is stripped using a ceramic diffusion separator (this process needs development, but will involve several stages of recycle)
• Heat from extracted Hydrogen is recovered to pre-heat fluid feedstock in a counter-flow heat exchanger.
• Hydrogen stripping is limited to only ~70% for economic reasons

• More pre-heated fluid feedstock is added, and stream goes to Solid Oxide Fuel Cell
• SOFC converts ~ 55% of chemical energy to Electricity (see research on SOFC's)
• ESSENTIAL feature is that cell works by Oxygen ions crossing membrane (not H- ions) hence CO2 waste is produced on feedstock side of cell (NOT mixed with N2 in air)

• Tailgas from SOFC goes to gas turbine to burn residual hydrocarbons and use heat
• GT exhaust is only CO2 + water, easily separated by cooling. Heat is recycled.
• GT drives compressor which compresses and liquefies CO2 for disposal.
• Remaining power from GT can be used for utilities or Power Gen.
• Waste Heat is used to power a Steam Turbine.

• Oxygen for process (Reformer and Gas Turbine) is produced by electrolysis of water
• Hydrogen by-product is added to output from Separator

• Produced hydrogen is exported or stored (underground?) until needed
• For peak power production, H2 can be converted to electricity in a conventional PEM cell.
