Abstract
Provided is a cooling structure for vehicle electrical components that is capable of solving problems due to water contained in intake air. Air used in an electricity generation reaction and air necessary for self-cooling is supplied to a fuel cell stack (11) via an intake duct (2). Dust and chemical substances in the air are removed by a dust/chemical substance filter (3) provided on the fuel cell stack (11) side within the intake duct (2). Furthermore, air and water are primarily separated by a water filter (4) provided in the intake duct (2) upstream by a prescribed distance in the air flow direction from the dust/chemical substance filter (3). Therefore, water in the intake air does not reach the dust/chemical substance filter (3) and the fuel cell stack (11), and various problems due to water contained in the intake air can be solved.
