摘要： An upper wing surface of a laminar-flow airfoil for decreasing an undesirable head-lowering pitching moment around an aerodynamic center of the airfoil. The upper wing surface includes: a convex front profile portion extending from a leading edge to a largest-thickness point located corresponding to 38% of a wing chord length. A convex central profile portion extends from the largest-thickness point to a position corresponding to 90% of the wing chord length at which a value obtained by dividing a thicknesswise difference between the position and the largest-thickness point by a distance in a direction of the wing chord from the largest-thickness point is equal to or smaller than 0.12. A concave rear profile portion extends from a position corresponding to 95% of the wing chord length to the trailing edge. The rear profile portion forms a pressure gradient is steeper than that formed by the central profile portion.

摘要： A fuel cell stack (10) includes a first sub-stack (12), a second sub-stack (14), and a third sub-stack (16) disposed in the flow direction of an oxidizing gas. An intermediate plate (18a) is interposed between the first and second sub-stacks (12, 14), and an intermediate plate (18b) is interposed between the second and third sub-stacks (14, 16). In this fuel stack (10), the flow of an oxidizing gas is set such that the oxidizing gas flows in series in the direction from the first sub-stack (12) to the third sub-stack (16). Between the sub-stacks additional oxidizing gas supplies (70,74) are provided through which oxidizing gas of lower humidity than the humidity of the oxidizing gas entering the first sub-stack is supplied. This arrangement allows an efficient management of the humidity water content of the oxidizing gas with sufficient moisturizing of the solid polymer membrane whilst avoiding excessive condensation of water vapour within the stack.

摘要： A fuel gas passage, an oxygen-containing gas passage, and a coolant passage extend through a fuel cell stack. Each of the fuel gas passage and the oxygen-containing gas passage is formed by serially connecting passages between the first through third fuel cell modules. The fuel gas flows through the fuel gas passage, and the oxygen-containing gas flows through the oxygen-containing gas passage from the first fuel cell module toward the third fuel cell module. The coolant passage is formed by serially connecting passages between the first through third fuel modules. The coolant flows through the coolant passage from the third fuel cell module toward the first fuel cell module. The direction of the flow of the coolant is opposite to the direction of the flows of the fuel gas and the oxygen-containing gas.
