Abstract

The invention concerns a method of generating electrical energy from biomass which is produced in a biomass-production module. The biomass is gassified in a reformer module to form a hydrogenous crude gas from which a purified gas with a higher hydrogen content is produced. Electrical energy is generated from the purified gas in a converter module. In this case, biomass with low sulfur and chlorine contents is produced by a suitable fertilizing of plants. The reformer module operates with at least one allothermic reformer, the dwell time of the biomass or crude gas in the reformer, and the temperature and pressure therein being set so that the alkali compounds can be removed from the reformer with any ash produced. Tar is gassified in the reformer to form carbon monoxide and hydrogen. A purified containing less than 1% carbon monoxide is produced in the crude gas processing module. The purified gas is reacted in at least one PEM fuel cell to produced electric current, the operating temperature of the fuel cell, and both the water content and pressure of the purified fuel gas being adapted to one another to produce an optimum flow density.
