Brennstoffzellenstapel mit einer Durchtrittsvorrichtung für ein Temperaturregulierungsmedium

摘要

A tube (18) having a passage (16) for passage of a temperature-regulating medium therethrough has a surface covered with an elastic insulating layer (104) which is coated with an insulating lubricant (106). The tube (18) is inserted in a through hole (14) which is defined in a fuel cell stack (10) in the direction in which generator cells (12) are stacked.
