Aerodynamic device for a motor-vehicle including a panel structure located under the front part of the motor-vehicle and elastically biased towards a raised position and configured to be moved towards a lowered position due to an airflow which invests the motor-vehicle during travel. The aerodynamic device includes a bag structure provided inside of a cavity for receiving in its interior the airflow which invests the motor-vehicle during travel, in such a way that above a predetermined threshold value of the motor-vehicle speed, the bag structure is inflated and pushes the panel structure towards its lowered position.

An electrolysis electrode and a preparation method therefor, an electrolysis apparatus, and a clothing treatment device. The electrolysis electrode includes a substrate, a transition layer, and an electrode catalytic material layer, and the transition layer is attached to the surface of the substrate, the electrode catalytic material layer is attached to the surface of the transition layer, and the thickness of the transition layer satisfies that: electrons can pass through the transition layer. The transition layer of the electrolysis electrode is relatively thin, so that electrons can pass through the transition layer due to a quantum tunneling effect, and thus the electrocatalytic performance of the electrolysis electrode is basically not affected. Furthermore, the transition layer plays the role of transition connection, and can greatly improve the phenomenon of cracks in the electrode catalytic material layer.
