  • Patent number: 8096109
    Abstract: A system including a fuel cell and an internal-combustion engine, particularly for a motor vehicle. Preferably, exhaust gas from the internal-combustion engine flows at least essentially around the fuel cell. Exhaust gas from the internal-combustion engine may also flow around an afterburner for the fuel cell exhaust gas and/or around a reformer for processing fuel. The fuel cell and/or afterburner and/or reformer may be arranged downstream of a purification system for the internal-combustion engine exhaust gases and may be essentially inside a pipe or the like carrying the latter. The fuel cell and the reformer may also be arranged upstream of an exhaust gas purification system. Part of the fuel cell exhaust gas flow may be fed to the internal-combustion engine for combustion, and exhaust gases from the fuel cell and/or the internal-combustion engine may transfer heat with the air for the fuel cell.
