A recombiner has a shield (5) positioned above a unit (2) for catalytic recombination of hydrogen in an accumulator with oxygen to form water.

The present invention relates to methods for gas phase reactant catalytic reactions. In particular the present invention relates to a method of hydrocarbon steam reforming, comprising: passing a reactant stream comprising steam and hydrocarbon into at leas...

Carbon monoxide contained in reformate gas is removed by a preferential oxidation reaction in a catalyst, two preferential oxidation reactors (20A, 20B) being disposed in series. Valves (7, 8) supply air containing oxygen as an oxidizing agent individually...

A reactor combines two heterogenic processes which are an endothermic catalytic process and an exothermic catalytic reaction. Reactants flow through a thin horizontal, porous catalytic reforming disc joined to an oxidation catalytic layer. The layer has in...

A fuel cell system is proposed which is provided with a CO oxidizer having a compact agitator executing uniform mixing. The fuel cell system is provided with a reformer (2) performing reformate reactions to produce a hydrogen-rich reformate gas containing ...

A temperature/reaction management system comprises a reformer system (86) and a mat material (80) fluidly coupled to a portion of the inlet (82) of the reforming zone of the reformer system (86). An inert material (92) and/or flame arrestor (90) can option...

Catalyst element (1) consists of a catalyst plate made of a porous material and a sturdy connecting element (3) whose side on the catalyst side is enclosed by and connected to the catalyst plate. Fixing devices (6) are provided on the exposed end of the co...

The invention relates to a device for treating a medium in a fuel cell system, comprising a reactor with a catalyst-containing region between a first subspace of the reactor and a second subspace of the reactor, wherein the catalyst-containing region is ar...
