Abstract: A method for assembling a bipolar plate by integral misalignment, a fuel cell stack with the bipolar plate and a power generation system are provided. The misalignment mode includes: misaligning the centers of mass and misaligning the centers of flow fields. The method can form a large-area synchronous undulation area or simultaneously form a plurality of synchronous undulation areas on the bipolar plate without changing a flow channel spacing. In the fuel cell stack, by the means that the bipolar plate is rotated 180° around an axis parallel to a thickness direction of the bipolar plate or rotated 180° around an axis parallel to a misalignment direction, the MEA is prevented from wrinkling, so as to avoid the blockage of a reactant flow channel and poor contact of a circuit.

Abstract: A bipolar plate, a fuel cell stack with the bipolar plate and a power generation system with the bipolar plate are provided. The bipolar plate includes a first polar plate and a second polar plate. The first polar plate includes a first side and a second side, and the second polar plate includes a third side and a fourth side. The first side of the first polar plate and the third side of the second polar plate have different flow fields. The bipolar plate further includes at least one synchronous undulation areas, which are the channels for the coolant to be introduced into and discharged out of the interlayer of the bipolar plate. The second polar plate is provided with a coolant diversion dike, which can guide the coolant to flow according to the preset route.

Abstract: The present invention provides a polymorph of a benzamide compound and a preparation method and applications thereof. The shown benzamide compound is 3-Bromo-N-[2,4-dichloro-6-[(methylamino)carbonyl]phenyl]-1-(3,5-dichloro-2-pyridinyl)-1H-pyrazole-5-carboxamide. The application of the polymorph of the compound in the preparation of the formulation exhibits excellent effect. The advantages of the polymorph A in aspects such as chemical stability, filterability, solubility, hygroscopicity, melting point, solid density and flowability can have a significant impact on the developments of the production method and a formulation and on the quality and efficacy of a plant treating agent.

Abstract: A bipolar plate with a coolant flow channel, includes a fuel flow field plate and an oxidant flow field plate. The bipolar plate includes an alignment area and at least two misalignment areas. In a fuel cell stack containing the bipolar plate, a coolant is enabled to flow from a coolant inlet channel to a coolant flow channel of one misalignment area without passing through a coolant flow channel of the alignment area. Also, the coolant is enabled to flow from a coolant flow channel of the other misalignment area to a coolant outlet channel without passing through the coolant flow channel of the alignment area.

Abstract: The present invention relates to the field of LED illumination, particularly to a high power LED illuminant based on heat pipe principle. The high power LED illuminant comprises a light emitting section, a liquid storing section with liquid electric-insulation-operating-medium stored therein and a heat sink. The liquid electric-insulation-operating-medium is drawn into the light emitting section by means of capillary force and then immerses the LED chips and thus directly cools down the LED chips. The electric-insulation-operating-medium takes in heat and turns into gas and then flows into the liquid storing section through capillary channels. The heat sink is used to cool down the electric-insulation-operating-medium so that it turns into liquid. When the LED chips generate heat during its operation, the electric-insulation-operating-medium flows into the heat sink after turning into gas by absorbing heat. The electric-insulation-operating-medium turns into liquid after giving out heat through the heat sink.
