A method of generating electric energy from biological raw materials. A biological raw material is used which is substantially free from sulphur of natural origin. A combustion gas is generated from biological raw materials in an oxidation reactor by partial oxidation. An oxygen/biological raw material proportion of ingredients and a gas phase temperature are maintained which ensure a combustible gas virtually free of nitrogen oxides. After removing suspended matter from the combustible gas in a separator, the combustible gas is converted into electric energy in fuel cells having a porous anode a porous cathode and, a suitable electrolyte.

Why it's free to use
- Filed March 11, 1993 and granted November 30, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 11, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 11, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
