Tailored heat transfer characteristic of fuel cell coolers

The thermal profile of one or more fuel cells (10) cooled by coolant flowing in coolant flow passageways (30, 31, 33, 34, 37-41, 45-50) is tailored by providing selected material (65, 68) adjacent a portion (33b) of the coolant passageway; the selected material has a different thermal transfer chara...

Beschreibung
Zusammenfassung:	The thermal profile of one or more fuel cells (10) cooled by coolant flowing in coolant flow passageways (30, 31, 33, 34, 37-41, 45-50) is tailored by providing selected material (65, 68) adjacent a portion (33b) of the coolant passageway; the selected material has a different thermal transfer characteristic than material surrounding other portions of the coolant passageway. The material may be more insulative or more conductive. The material may be wrapping (65), such as shrink wrap, about a coolant tube, or it may be altered material (68) in a molding material.
