Abstract: Aspects of the disclosure include a membrane-electrode-assembly (MEA) with a trimmed proton-consuming electrode. An exemplary vehicle includes an electric motor, a battery, and a proton exchange membrane electrochemical cell. The electrochemical cell includes a proton-generating electrode, a proton-consuming electrode, and a membrane positioned between the proton-generating electrode and the proton-consuming electrode (the proton-generating electrode, proton-consuming electrode, and membrane collectively defining a membrane-electrode-assembly), and a gas diffusion layer positioned in direct contact with the proton-consuming electrode. The proton-consuming electrode is trimmed with respect to a first edge of the membrane and with respect to a second edge of the membrane. The first edge is orthogonal to the second edge. The proton-consuming electrode is trimmed using laser ablation at a focus depth that bypasses the membrane.

Abstract: The present application provides a control method and a control device of an indoor fan of an air conditioner, and an air conditioner. When the air conditioner operates in a cooling mode, when an indoor temperature reaches a set temperature, and it is detected that the number of times of frequent start-stop of a compressor is greater than or equal to the set number of times within a set time, it is determined that the air conditioner enters an operating stage of maintaining an indoor set temperature, and the compressor is no longer controlled to start and stop, but the indoor fan is controlled to operate in reverse at different rotational speeds based on different coil temperatures Tz of an indoor heat exchanger, an air volume output by the indoor fan is less than an air volume output when the indoor fan operates in forward.

Abstract: Detailed herein is a control method for preventing a false alarm of an air conditioner anti-overflow water level switch. Under the condition that an air conditioner is operating in a cooling or dehumidification mode, when an alarm of the water level switch is triggered at startup, the air conditioner continues normal operation, a condensed water drainage volume per unit time during cooling of the air conditioner is acquired through theoretical calculation, and a time required for a water level of condensed water to reach an OFF position of the anti-overflow water level switch is calculated based on a bottom area of a water receiving tray. After the air conditioner operates for a corresponding duration, a drainage pump is activated at a maximum speed to gradually lower the water level of the condensed water until the water level reaches an ON position of the anti-overflow water level switch.

Abstract: A primary heating band is applied to a weld to control a microstructure and hardness of the weld and uniformity of the structure to realize micro-control of the residual stress; an auxiliary heating band is applied a certain distance away from the weld to generate compressive stress on an inner surface of the weld to realize macro-control of the compressive stress. Reinforcement with a rib plate is eliminated, and a labor intensity and a construction period are reduced. The method reduces deformation near the weld and transfers the largest deformation to a non-weld zone; by applying the auxiliary heating and strictly controlling a time interval between primary heating and auxiliary heating, the structure is improved and the welding residual stress is controlled at the same time; a local heat treatment effect is optimized, and a small tensile stress or compressive stress is generated on the inner surface of the weld.

Abstract: A fuel cell stack that includes a gas diffusion media for the end cells in the stack that has less of an intrusion into the flow field channels of the end cells that the other cells, so as to increase the flow rate through the flow channels in the end cells relative to the flow rate through the flow channels in the other cells. A different diffusion media can be used in the end cells than the nominal cells, where the end cell diffusion media has less of a channel intrusion as a result of diffusion media characteristics. Also, the same diffusion media could be used in the end cells as the nominal cells, but the end cell diffusion media layers could be thinner than the nominal cell diffusion media layers. Further, a higher amount of pre-compression can be used for the diffusion media in the end cells.
