STACK STRUCTURE FOR AN ELECTROCHEMICAL ENERGY CONVERTER, AND METHOD FOR PRODUCING THE STACK STRUCTURE

原文（中国語）

The present invention relates to a stack structure () for an electrochemical energy converter (), comprising bipolar plates (), membrane electrode units (), a process fluid routing structure () for routing process fluid in a stacking direction (), frame seals (), which are respectively attached to the membrane electrode unit () in an edge region of a membrane electrode unit (), process fluid seals () for sealing an edge area of the process fluid routing structure (), wherein the process fluid seals () each comprise an inner seal portion (), which, viewed in a transverse direction (), is positioned between the process fluid routing structure () and the membrane electrode units (), edge seals () for sealing an edge region of the frame seals () and/or an edge region of the bipolar plates (), and spacer elements (), positioned and/or configured in the stacking direction () between two inner seal portions () and each having a through-opening () for routing process fluid in the transverse direction () from the process fluid routing structure () to the respective membrane electrode unit (). The invention further relates to a method of manufacturing such a stack structure ().
