Abstract
The air-cooled thermal management of a fuel cell stack is disclosed. One disclosed embodiment comprises a cooling plate apparatus for an air-cooled fuel cell stack, where the cooling plate comprises a body configured to receive heat from one or more fuel cells in thermal communication with the body, and airflow channels formed in the body and configured to allow a flow of a cooling air to pass across the body. An insulating structure is disposed in the airflow channels, wherein the insulating structure has decreasing thickness from a cooling air inlet toward a cooling air outlet.
