Abstract
A method for exhausting a substance through a port in a lid of a chamber, comprising conducting the substance through a tube within the port, which tube is more resistant to corrosion by the substance than is the port, and supporting the tube on a support means extending into the interior of the port, while cooling the support means to a temperature such that it too is more resistant to corrosion by the substance than is the port. A cell lid having a metallic port, metallic protrusion means extending into the port, cooling means for extracting heat from the protrusion means, and a carbon or ceramic tube supported on the protrusion means.
