Thermal Electric Conductive HHO PEM Fuel Cell Graphite Bipolar Plates

Graphite is one of the most resistant materials currently known. Its melting point is 3850°C±50°C and its boiling point is 4250°C. It is 10S under the 7000°C ultra-high temperature arc, the loss of graphite is minimal, and the loss of graphite is 0.8% by weight. It can be seen that the high temperature resistance of graphite is outstanding. At the same time, graphite has good thermal shock resistance, that is, when the temperature suddenly changes, the coefficient of thermal expansion is small, so it has good thermal stability. When the temperature changes rapidly and rapidly, it will not produce cracks.

Features

1,high temperature: Graphite is one of the most known high temperature materials. Its melting point is 3850°C±50°C and its boiling point is 4250°C. It is 10S under the 7000°C ultra-high temperature arc, the loss of graphite is minimal, and the loss of graphite is 0.8% by weight. It can be seen that the high temperature resistance of graphite plates is outstanding.

2,special thermal shock resistance: graphite has a good thermal shock resistance, that is, when the temperature changes abruptly, the thermal expansion coefficient is small, and thus has a good thermal stability, in the rapid change of temperature and heat, will not crack

3,thermal conductivity and conductivity: graphite has good thermal conductivity and conductivity. Compared with general materials, its thermal conductivity is quite high. It is 4 times higher than stainless steel, 2 times higher than carbon steel and 100 times higher than normal non-metal.

4,Lubricity: The lubricating property of graphite is similar to that of molybdenum disulfide, and the coefficient of friction is less than 0.1. Its lubricating properties vary with the size of the scales. The larger the scales, the smaller the coefficient of friction and the better the lubricity.

5,chemical stability: Graphite plate at room temperature has a good chemical stability, acid, alkali, resistant to organic solvent corrosion.
