Problems solved by technology
There are problems such as low catalytic activity and easy loss of active ingredients of the catalyst, that is, the service life of the catalyst is very short, the catalytic active components and structure are unknown, and the mechanism is unclear (M.Lefevre et al.J Phys Chem, B, 2000, 104 : 11238~11247)
The catalyst catalyzes molecular oxygen, mainly 2e reduction, among which, the low catalytic activity is the biggest obstacle encountered in its application process

The invention provides a controllable pore diameter two-dimensional reticular metal phthalocyanine polymer. The general formula thereof is as shown on the right: M in the formula is transition metal ions or rare-earth ions. The application of the polymer is being used as a catalyst for the cathode of a fuel cell.
Description
technical field The invention relates to a mesh porous material formed by metal phthalocyanine polymer and its application. Background technique Domestic and foreign peers agree that the biggest obstacle to the industrialization of fuel cells is high cost and low durability (of course there are other problems to be solved). In the high cost, in order to operate efficiently and stably, a large amount of platinum catalysts are used in the membrane electrode (MEA) and occupy a large share. According to literature reports, to achieve the best efficiency, the amount of platinum needs to be about lgPt / kW. In addition, platinum catalysts also suffer from resource constraints. In order to solve this problem, there are two schemes that can be implemented: first, increase the utilization rate of platinum and reduce the consumption of platinum. The target of the US Department of Energy in 2010 is 0.2gPt / kW. However, as the platinum loading decreases, the efficiency of the battery wi...
