Method for start-up and shut-down of a fuel-cell installation

摘要

A starting process for a fuel cell comprising a reformer (1) converting natural gas and steam into hydrogen an other products and a catalytic stage (2) in steady operation comprises a phase (A) in which the reformer and catalyst stage are fed exclusively with warm air, a phase (B) in which air and steam are supplied, a phase (C) supplying steam only and a phase (D) in which natural gas and steam are supplied in a transition to steady operation. An independent claim is also included for a shutdown process having similar phases.
