dynamic pressure of a relative airstream at least partly forces
the coolant into the cooling system.
The examiner relies upon the following references as
evidence of obviousness:

Appellants' claimed invention is directed to an electrical
vehicle, and method for operating the fuel cell system for an
electric vehicle, wherein the fuel cell system comprises an
integrated cooling system that is arranged in the vehicle so that
the dynamic pressure of a relative airstream forces coolant,
i.e., air, into the cooling system. According to appellants,
"[a] fuel cell stack is preferably located at the radiator of the
vehicle and the relative wind directly cools the individual fuel
cells" (page 3 of Brief, second paragraph).
Appealed claims 14-17, 19, 29 and 30 stand rejected under
35 U.S.C. § 103 as being unpatentable over Fletcher in view of
