Claim 10:
11. A vehicle comprising:
a combustion engine with cylinders that are connected to a fuel inlet and to an exhaust outlet, the exhaust outlet being in fluid contact with a catalyst/steam reforming assembly comprising a heat exchange module comprising:
a corrugated top heat exchange substrate and a corrugated bottom heat exchange substrate, the substrates being spaced apart in a transverse direction (T), each substrate having ridges and channels that extend in a length direction (L), the channels and ridges of the top substrate extending parallel to the channels and ridges of the bottom substrate,
tubes extending in a width direction (W) between the top and bottom substrates, in heat exchanging contact with the ridges, the width direction (W) being oriented transversely to the length direction (L) of the channels and the ridges, from an inflow side to an outflow side,
a top and a bottom casing member comprising casing surfaces adjacent the top and bottom substrates and having at the inflow and outflow sides a transverse side wall with slits oriented in the transverse direction (T) and accommodating the tubes,
the side walls of the top and bottom casing members overlapping and being mutually connected by soldering or brazing,
exhaust gases being led through the channels and alcohol and steam through the tubes,

an evaporator that is in heat exchanging contact with the exhaust gases,
a water and ethanol supply unit flowing water and ethanol through the evaporator for forming water and ethanol steam, the water and ethanol steam being passed into the tubes, and
a reformed fuel duct connected to an outflow side of the tubes and being connected to a fuel inlet of the cylinders.
