Electrolytic cell bipolar plate
The bipolar plate is formed by welding the anode metal plate and the cathode metal plate together, and the edges of the cathode side and the anode side plate will have grooves to arrange sealing rings to prevent the reaction gas and the cooling liquid from escaping each other, and at the same time prevent the reaction gas and the cooling liquid from leaking. Bipolar plate, also known as collector plate, is one of the important components of fuel cell. It has the following functions and properties: separating fuel and oxidant to prevent gas permeation; Collecting and conducting current with high conductivity; The designed and processed flow channel can evenly distribute gas to the reaction layer of the electrode for electrode reaction. Can discharge heat and keep the battery temperature field uniform; Corrosion resistance; Shock and vibration resistance; Thin thickness; Light weight; At the same time, the cost is low, easy to machine, suitable for batch manufacturing, etc. Bipolar plate materials can be roughly divided into three categories: carbonaceous materials, metal materials and metal and carbon composite materials.
Wind turbine blade lightning protection net
In the current wind power market, the composite materials, because of its unique performance advantages to become the mainstream of wind turbine blades, in order to achieve high-strength and lightweight. The traditional flashing system can not provide complete protection. In the cases of actual lightning damage, the lightning strike can bypass the flashing device and hit the blade, which is very common.
