Power Generation System Using Fuel Cell
First Claim
1. Power generation system comprising:
- a combustion engine (12), an electrical power supply unit (36, 24, 26;
50;
52;
54) at least partly driver by exhaust fumes generated by said combustion engine, and a reversely operated fuel cell (30) connected to the electrical power supply u and the combustion engine, wherein said reversely operated fuel cell is provided with electrical power by said electrical power supply unit and is arranged to emit hydrogen to said combustion engine for use in the operation thereof.

Abstract
The present invention relates to a power generating system, a motorised device comprising such a power generation system as well as a method of lowering the fuel consumption of a combustion engine (12). The power generation system comprises a combustion engine (12), an electrical power supply unit (18, 26) that is at least partly driven by exhaust fumes generated by said combustion engine and a reversely operated fuel cell (30) connected to the electrical power supply unit and the combustion engine. The reversely operated fuel cell is provided with electrical power by the electrical power supply unit and is arranged to emit hydrogen to the combustion engine for use in the operation thereof. In this way fuel consumption is lowered.
