Abstract
An end-cooler assembly for a fuel cell includes a cooler having a coolant tube array. A composite material includes flake graphite and hydrophobic polymer. The composite material surrounds the coolant tube array and provides a first side. A flow field is formed in the first side. A thermal dam is embedded in and is entirely surrounded by the composite material. The thermal dam is arranged between the coolant tube array and the flow field. The coolant tube array, composite material, flow field and thermal dam comprise a unitary, monolithic structure bound together by the composite material.
