Abstract
A fuel cell stack includes a number of modularized plate structures including an anode plate, a cathode plate, water coolant plates and air coolant plates. The anode and cathode plates are designed to form hydrogen and air channels that allow for uniform distribution and even flow of hydrogen and air through the channels with the channels of each particular plate having substantially identical length in order to enhance electrochemical reaction between hydrogen and oxygen contained in the air with respective catalysts in the fuel cell stack. Also a sufficient amount of air is allowed to flow through the cathode plate to enhance output power of the fuel cell stack. The coolant plates adapt a split design, which introduces turbulence in the coolant channels to enhance heat removal.
