Abstract
Official abstract text for this publication.
A method is provided for purging a fuel cell. The method is characterized by suctioning the purge gas through the fuel cell by use of low pressure.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for purging a fuel cell, the method comprising the acts of: suctioning purging gas through the fuel cell, wherein the suctioning of the purging gas through the fuel cell occurs via a negative pressure; the purging gas is suctioned in via a fuel-cell exhaust-gas outlet or a purging-gas supply and the purging gas suctioned in via the fuel-cell exhaust-gas outlet or the purging-gas supply is delivered through a fuel-cell exhaust-gas line to the fuel cell. 2. The method according to claim 1 , wherein, during the suctioning of the purging gas through the fuel cell, a delivery device for cathode gas is operated in a normal delivery direction. 3. The method according to claim 1 , wherein, the purging gas suctioned through the fuel cell is delivered out via a purging-gas outlet provided in a cathode-gas supply of the fuel cell. 4. The method according to claim 1 , wherein the negative pressure is generated by operating a delivery device of the fuel cell in a reverse direction. 5. The method according to claim 1 , wherein after deactivation of the fuel cell, a delivery direction is initially maintained for one to ten seconds. 6. The method according to claim 1 , wherein water is condensed out of fuel cell exhaust air and/or out of the purging gas before suctioning the purging gas through the fuel cell via the negative pressure.
