Problems solved by technology

Electric heating generally uses the electricity generated by hydrogen fuel cells to supply heating. This method will reduce the efficiency of methanol hydrogen generation power generation, and direct use of electric heating methods such as heating belts, heating rods, and heating rods is likely to cause hot spots, which will affect the catalyst itself. life span

If the direct combustion of fuel is used, the loss of electric energy can be avoided to a certain extent, but it is very easy to generate hot spots, which will affect the reaction and reduce the life of the catalyst.
