Abstract

A fuel-cell-powered aircraft system has integrated air-cooled fuel cell stacks positioned within an interior space of at least one wing of an aircraft. An airflow path is positioned in contact with at least a heat exchanger of the fuel cell stack. The induced flow of air through the airflow path cools the heat exchanger. The efficiently-induced flow of air for cooling the fuel cell stack has a zero or minimal drag penalty.
