PCT No. PCT/DE89/00209 Sec. 371 Date Nov. 16, 1990 Sec. 102(e) Date Nov. 16, 1990 PCT Filed Apr. 5, 1989 PCT Pub. No. WO89/10010 PCT Pub. Date Oct. 19, 1989.The invention relates to a system for generating electric energy from fuels by means of electrochemically acting fuel cells. In order to achieve an operation of a system which is efficient and not harmful to the environment, heat exchangers and at least one gas washing unit are coupled to the fuel cells. The heat exchanger is contructed such that the heat quantities occurring during the process are reutilized for the operation of the fuel cells. The gas washing unit is used for the precipitation and recovery of residual fuel components contained in the fuel waste gas and of expensive catalyst gas which are recycled to the fuel cells. An additional gas washing unit and additional precipitating unit are controlled by a microprocessor to increase the efficiency of the system while energy is generated in a manner which leaves practically no residues and is not harmful to the environment.
