The engine comprising an intake manifold for receiving a first fuel and an exhaust manifold for releasing an exhaust gas. The reforming reactor includes a first end portion, a second end, a wall having an outer surface and an inner surface. The inner surface defines an interior cavity for receiving the first fuel, a second fuel, reactants for the first fuel, or combinations thereof. The exhaust manifold of the system is sized and shaped for receiving a portion of the reforming reactor such that the exhaust gas flows along a surface of the reforming reactor within the exhaust manifold.
Reactor incorporating a heat exchanger
A reactor containing a heat exchanger is disclosed, which can be operated with co-current or counter-current flow. Also disclosed is a system that includes a reactor having a reformer and a vaporizer, a fuel supply, and a water supply. The reactor includes a source of combustion gas, a reformer operative to receive reformate, and a vaporizer operative to receive water. The reformer and vaporizer each include a stack assembly formed by a combination of separator shims and channel shims. The separator shims and channel shims are stacked in a regular pattern to form two sets of channels within the stack assembly. One set of channels will have vertical passageways at either end and a horizontal flowpath between them, while the other set of channels has only a horizontal flowpath.
Fuel cell module
