摘要:
A PEM fuel cell with a heating element, a method for operating the PEM fuel cell system, and a PEM fuel cell system includes the heating element having an integrated thermosensor that, substantially, can prevent the temperature of the cell/system from dropping below the freezing point of the electrolyte.
摘要:
A honeycomb body assembly includes a honeycomb body with channels through which a fluid can flow. The channels extend between two end faces. At least one sensor extends at least partly into the honeycomb body. A first partial volume of the honeycomb body is defined between a first end face and the at least one first sensor. The honeycomb body has a lower capacity for oxygen in the first partial volume than in at least one further partial volume. An exhaust system with a space-saving configuration of such a honeycomb body is also disclosed.
摘要:
A catalyst carrier body has a geometrical longitudinal axis, a honeycomb body and a housing. A corrugated casing with an outer side and an inner side is disposed between the honeycomb body and the housing. The corrugated casing is connected to the housing at attachment sections on the outer side thereof by brazing. The attachment sections lie substantially on a common circumferential line and have the narrowest possible width in direction of a longitudinal axis. The attachment sections have an overall surface area permitting them to securely hold the honeycomb body under operating conditions. A high retention degree for the connection between the honeycomb body and housing can thus be achieved even with a shrinking of the diameter of the honeycomb body at end sides during the service life thereof.
