DEVELOPMENT OF A NEW NANOCOMPOSITE FOR ITS USE AS ELECTROCATALYST IN PROTON EXCHANGE MEMBRANES FUEL CELLS (PEMFC)
WO2019053312
A method that makes it possible to obtain a new catalyst in the electrolysis used by PEMFCs, replacing the current platinum materials, which are much more expensive and scarce. During the process of obtaining the nanocomposite developed, low-cost materials are used, relatively low temperatures are used, no solvents are required and the process takes place in short times. In addition, the material obtained is very stable and has structural characteristics that allow it to have a high electrocatalytic activity, much higher than those reported so far with similar compounds. Therefore, this new nanocomposite solves the problems existing up to now, allowing the obtaining of a material with a high electrocatalytic capacity and the reduction of production costs, thus responding to market demands.
Applications: The invention applies to the energy sector market, mainly to companies that can use the nanocomposite in PEMFC that can be integrated into cars, portable equipment, etc. Advantages: The developed nanocomposite material has the following advantages: - Improvement of electrocatalytic activity. The structural characteristics of the nanocomposite causes an electrocatalytic activity much higher than those reported up to now. - A considerable reduction in costs, due to the convergence several factors: Obtain the precursor with economical materials and in a solvent-free process. Obtain the nanocomposite in a relative short time and at relatively low temperature. Calcination of the nanocomposite is done using nitrogen, which is much cheaper and safer than other gases used in other processes, such as a mixture of argon and hydrogen
