| 摘要 |
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 fuel gas with a high hydrogen content is formed in a crude gas processing module, electrical energy being generated from the purified fuel gas in a converter module. In this case, biomass with low sulphur and chlorine contents is produced by suitable fertilizing of plants. The reformer module operates with at least one allothermic reformer, the dwell time of the biomass and/or crude gas in the reformer and the pressure and temperature therein being set so that alkali compounds can be removed from the reformer with any ash produced. Tar is gassified in the reformer to form carbon monoxides and hydrogen. A purified fuel gas containing fewer than 1 % carbon monoxides is produced in the crude gas processing module. The purified fuel gas is converted into electric current by at least one PEM fuel cell, the operating temperature of the fuel cell, the water content of the purified fuel gas and the pressure of the purified fuel gas being adapted to one another so as to produce an optimum flow density. |
