Abstract
Disclosed are a metal separation plate for a fuel cell stack, which includes protrusion patterns each having an air path opened in a short-side direction or protrusion patterns each having an air path of which one side is opened and the other side is closed, and can not only improve cooling performance and stack performance without a separate cooling plate mounted therein, and but also improve humidification performance of a membrane electrode assembly (MEA) by blocking moisture leaking from the inside of the closed air paths, and a fuel cell stack having the same.
