In a hybrid vehicle with fuel cells and an engine mounted thereon as energy output sources, the technique of the present invention adequately changes a working energy output source according to a driving state of the hybrid vehicle. The hybrid vehicle has the engine and a motor, both enabling power to be output to an axle. The hybrid vehicle also has fuel cells as a main electric power supply for driving the motor. The technique of the present invention changes the working energy output source between the fuel cells and the engine, in order to reduce the output of the fuel cells with consumption of a fuel for the fuel cells. With a decrease in remaining quantity of the fuel, the technique narrows a specific driving range, in which the motor is used as the power source. The technique also causes the engine to drive the motor as a generator and charges a battery not with electric power of the fuel cells but with electric power generated by the motor. This arrangement effectively prevents the fuel for the fuel cells from being excessively consumed in one driving mode. The fuel cells can thus be used preferentially in a specific driving state of the hybrid vehicle where the fuel cells have a high efficiency.

A fail-safe lug is carried by an engine frame member and receives a clevis carried by an engine mount member. The mount member includes side links that transmit transverse loads between the engines and the airframe and a thrust link that transmits axial, engine thrust loads between the engine and the airframe. A fail-safe pin is carried by the clevis and has an outer diameter that is smaller than an aperture in the lug and through which the pin passes, so that no loads are imposed on the fail-safe pin in normal operation. When one or more of the links are no longer capable of transmitting loads, the fail-safe arrangement becomes operative to accommodate the loads transmitted between the engine and the airframe.
