Reactor unit used for steam reforming a gas mixture stream containing hydrocarbons in fuel cells has sheet layers with heating fluid channels and gas mixture channels arranged to form a specified angle

摘要

Reactor unit has sheet layers (2) partially forming a honeycomb structure (3) through which a fluid can flow. The layers having heating fluid channels (4) arranged parallel to the heating fluid direction (5) and gas mixture channels (6) arranged parallel to the gas mixture direction (7). The heating fluid channels and the gas mixture channels form an angle of 45-135, especially 90 deg . Preferred Features: The sheet layers are structured so that the gas mixture channels are arranged with the heating fluid channels between two sheet layers. The sheet layers forming the gas mixture channels have a catalytically active coating. The reactor unit further comprises an electrical heater.
