Abstract

A system for reducing harmful substances in engine exhaust gases includes a fuel cell, which is adapted to generate electrical energy and a steam-containing fuel cell exhaust gas during operation. A fuel tank serves to store fuel which is to be supplied to an engine during operation. A condensing device is connected to an exhaust gas outlet of the fuel cell so that steam-containing fuel cell exhaust gas is supplyable to the condensing device. The condensing device is adapted to convert the steam contained in the fuel cell exhaust gas into the liquid state of aggregation by means of condensation and to introduce the water obtained as a result of the condensing process into the fuel in order to form a water/fuel mixture. A water/fuel mixture line is connected to the engine so that a water/fuel mixture is supplyable to the engine.
