Description

technical field [0001] The invention relates to the technical field of hydrogen fuel cell manufacturing, in particular to a hydrogen fuel cell manufacturing equipment and operation method. Background technique [0002] A hydrogen fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy. The basic principle is the reverse reaction of electrolyzed water. Hydrogen and oxygen are supplied to the anode and cathode respectively. After the hydrogen diffuses outward through the anode and reacts with the electrolyte, electrons are released to reach the cathode through an external load. Like ordinary batteries, electrodes are also divided into anode and cathode. The main function of the diaphragm is to separate the oxidant from the reductant. The current collector mainly plays the role of collecting current and channeling the reaction gas. The hydrogen will decompose electrons and protons, the protons will pass th...

Problems solved by technology

[0003] The main structure of a hydrogen fuel cell includes electrodes, diaphragms, and current collectors. Among them, high-density composite graphite is used for battery separators. Sangao graphite is corrosion-resistant, has good conductivity, and has good strength. Now, the existing commercial fuel cell catalysts Platinum-carbon composites are mainly used, which are supported catalysts dispersed by platinum nanoparticles on carbon powder carriers, but this catalyst cannot meet the full promotion of fuel cell vehicles. Graphite separators can complete the recycling of platinum catalysts. The communication membrane is the central part of the fuel cell. It not only plays the role of blocking the electrolyte, but the graphite plate of the hydrogen fuel cell is also responsible for the transmission of protons. The thickness of the proton communication membrane is only 50-180um, which has strong selective permeability and only allows hydrogen The passage of ions blocks the passage of electrons, and at the same time has a moderate water content, which can stabilize the occurrence of oxidation, recovery and hydrolysis reactions

[0004] The existing separators for hydrogen fuel cells are cumbersome to produce and process because the way to achieve a sufficient degree of airflow over each cell of the stack while keeping the overall weight of the stack low is by using corrugated Cathode separator, which is used both to form the electrical connection to the cathode side of the fuel cell electrolyte and to provide a path for air flow across the underlying diffusion layer, and for corrugated separators, usually both sides of the separator require machining, The existing processing technology cannot process both sides of the partition in one process at the same time, and can only process one side and one side. After completing the single-sided processing, it needs to return to the processing workshop to process the unprocessed partition on the other side, resulting in cumbersome processing , affecting work efficiency
