METHOD FOR OPERATING A REFORMER UNIT WITH A COLD START CLEANING AND REFORMER UNIT WITH A COLD START CLEANING

摘要

The invention relates to a method for operating a reformer unit (1), for the preparation of a gaseous product stream (2), containing hydrogen, during a starting phase in energy generation by means of a fuel cell (3), whereby a parameter is determined which is proportional to a concentration of a noxious component in a product stream (2) and the product stream (2) is either fed to a fuel cell (3), or disposed of, according to the concentration of noxious component. The invention further relates to a reformer unit (1), which works according to the above method. The method and the reformer unit (1) are characterised in that the noxious materials occurring in a product stream (2) are kept away from a fuel cell (3) in a simple and economical manner.
