Abstract: A vehicle drive device and a control method therefor are provided. The vehicle drive device includes: a power source including a first rotating electrical machine (MG2); a second rotating electrical machine (MGF); a differential unit including three rotating elements to which a first output shaft, a second output shaft, and the second rotating electrical machine (MGF) are connected; and an electronic control device. The electronic control device regeneratively controls the first rotating electrical machine (MG2) and the second rotating electrical machine (MGF) in such a manner that negative torque is applied to the first output shaft and the second output shaft, when performing regenerative control by the second rotating electrical machine (MGF) in a drive mode in which torque from the power source is distributed to the first output shaft and the second output shaft by controlling torque of the second rotating electrical machine (MGF) during deceleration of a vehicle (ST7, ST8, ST10, ST11).

Abstract: PROBLEM TO BE SOLVED: To provide means for substantially increasing catalyst activity and/or increasing gas distribution in carbon carriers to substantially prevent the increase in fuel cell gas diffusion resistance in connection with an electrode catalyst for a fuel cell.SOLUTION: The present invention relates to an electrode catalyst for a fuel cell, which comprises: carbon carriers having pores; and catalyst particles including platinum or a platinum alloy and supported by the carbon carriers. The pores of the carbon carriers have a pore mode size in a range of 2.1-5.1 nm. As to the pores of the carbon carriers, the total pore volume is in a range of 21-35 cm/g. The distance between the catalyst particle and the surface of the carbon carriers is in a range of 2.0-12 nm, which is a distance at 50%-cumulative frequency.SELECTED DRAWING: Figure 1
