Abstract
A fuel cell stack that includes: stacked cells that generate electricity; an exchange plate disposed at a first side of the stacked cells, having a channel in fluid communication with an injection flow path and a discharge flow path, which extend between the cells; and a pump that is disposed at an opposing second surface of the stacked cells, to force coolant (air) through the injection flow path, the exchange plate, and the discharge flow path.
