A fuel cell system comprising a fuel cell stack, an evaporator for evaporating a mixture of methanol and water to be forwarded through a catalytic reformer for producing portions of free hydrogen. The fuel cell stack being composed of a number of proton exchange membrane fuel cells each featuring electrodes in form of an anode and a cathode for delivering an electric current. The system provides an enhanced catalytic reformer for a fuel cell system, which enables a compact design of the reformer for integration into a flat, rack mountable system.

Systems and methods are provided for improving the flow distribution in the high temperature zone of a cyclic flow reactor, such as a reverse flow reactor. The systems can include a plurality of mixing plates that can facilitate mixing of flows that have been maintained separately until a mixing location. Based in part on the use of a plurality of mixing plates, methods are provided for operating a reverse flow reactor with a temperature profile that has improved uniformity across the cross-section of the reactor. In some aspects, a flame diffuser can be included downstream from the plurality of mixing plates to further improve the uniformity of the temperature distribution.

Disclosed is a process for the catalytic thermal decomposition of ammonia into hydrogen and nitrogen by contacting ammonia at a temperature of at least 500 C. with a porous ceramic layer which comprises nickel. Also disclosed is a reactor for carrying out the process.

The reactor has a heat exchanging body which includes therein a heat medium flow channel in which heat medium fluid is caused to flow, a reaction flow channel in which a reaction fluid containing a first reactant (and a second reactant) is caused to flow, and a supplement channel for supplying a second reactant at an intermediate portion of the reaction flow channel. A catalyst is provided in the reaction flow channel and promotes the reaction in the reaction fluid. The heat exchanging body has a plurality of holes through which the supplement channel communicates with the reaction flow channel. Steam reforming can be performed using water vapor and hydrocarbon as the first and second reactants.
