Filter element having two filter medium bodies arranged one inside the other

Abstract

A filter element has first and second filter medium bodies, wherein one of the first and second filter medium bodies is arranged inside of the other one of the first and second filter medium bodies, and wherein the filter medium bodies are flowed through sequentially. An end plate is arranged at an end face of the filter element. At least the second filter medium body has a folded filter medium with end face edges at the end face. A side band seals the end face edges of the folded filter medium of the second filter medium body at the end face. The side band is embedded at least partially in the end plate. The filter element may be a cathode air filter of a fuel cell with an anode, a cathode, and electrolyte between the anode and the cathode, and the filter element configured to guide air to the cathode.
