Abstract: A heat exchanger has partitioning means for dividing a header tank such that a first space and a second space of a tank main body are arranged in a longitudinal direction of the header tank. An annular outer peripheral seal surface is provided around a tube bonding surface of a core plate of the header tank over an entire perimeter thereof and is provided with a gasket. A partitioning seal surface is provided to the tube bonding surface at a position corresponding to the partitioning means, and is provided with the gasket. The gasket seals between the core plate and the partitioning means. The partitioning seal surface is positioned on a plane identical with a plane of the outer peripheral seal surface. A part of the gasket, which is held by the core plate and the tank main body therebetween, has a uniform thickness.

Abstract: A fuel cell system is provided including heating means for heating up heat medium that exchanges heat with a fuel cell, and in which the fuel cell is warmed up by the heat medium heated by the heating means. The system includes: flow rate detecting means for detecting a flow rate of the heat medium flowing through the heating means; and heat controlling means for controlling the heating means based on the flow rate of the heat medium detected by the flow rate detecting means. With this arrangement, it is possible to prevent overheating of the heat medium in the fuel cell system in which the heat medium is heated to warm up the fuel cell.

Abstract: A heat exchange portion is configured by arranging a condenser for air conditioning, an EV radiator, and a FC radiator in one plane substantially perpendicular to a direction in which a fuel cell vehicle moves, at a front portion of the fuel cell vehicle, in order of an operating temperature, from an upper position to a lower position. A fan is provided behind the heat exchange portion such that a center thereof is closer to the condenser than to the FC radiator. In addition, a fan shroud is provided, in which plural ram pressure holes are formed in a portion which covers the FC radiator.
