技术领域technical field
本发明涉及燃料电池技术领域，具体涉及一种双极板树脂组合物、制备方法、双极板、燃料电池和车辆。The invention relates to the technical field of fuel cells, in particular to a bipolar plate resin composition, a preparation method, a bipolar plate, a fuel cell and a vehicle.
背景技术Background technique
燃料电池高效的将储存在燃料(如氢气、甲醇等)中的化学能转化为电能，是一种无碳排放、环境友好的发电方式。它的发电原理是在燃料电池内发生电化学反应，是将一个氧化还原反应分为燃料(如氢)的氧化和氧化剂(如氧)的还原两个半反应，中间用电解质膜分开，离子在电解质膜内迁移，电子通过外电路做功。燃料电池除了电解质膜外还有双极板、气体扩散层和催化剂层等部件。Fuel cells efficiently convert chemical energy stored in fuels (such as hydrogen, methanol, etc.) into electricity, and are a carbon-free, environmentally friendly way of generating electricity. Its power generation principle is that an electrochemical reaction occurs in a fuel cell, and a redox reaction is divided into two half-reactions, the oxidation of fuel (such as hydrogen) and the reduction of oxidant (such as oxygen). Electrolytes migrate within the electrolyte membrane, and electrons do work through an external circuit. In addition to the electrolyte membrane, the fuel cell also has components such as bipolar plates, gas diffusion layers and catalyst layers.
目前，燃料电池所用的极板材料主要包括石墨、金属以及膨胀石墨等。At present, the electrode materials used in fuel cells mainly include graphite, metal and expanded graphite.
石墨是最早应用于的燃料电池双极板材料，石墨双极板具有良好的耐蚀性，与碳纤维扩散层之间有很好的亲和力等优点，可以满足燃料电池长期稳定运行的要求。但是，石墨的孔隙率大、力学强度较低、脆性大。另外，石墨板采用传统机加工，工艺繁琐、成本偏高、不利于批量生产。金属(铝、钛、镍、不锈钢)及其合金(铝合金、钛合金等)制备的双极板解决石墨板的脆性的缺点，适合批量化生产,缺点主要是抗腐蚀差、与电极扩散层接触电阻大，必须经过表面处理，造成成本上升。Graphite is the earliest used fuel cell bipolar plate material. The graphite bipolar plate has the advantages of good corrosion resistance and good affinity with the carbon fiber diffusion layer, which can meet the requirements of long-term stable operation of fuel cells. However, graphite has high porosity, low mechanical strength and high brittleness. In addition, the graphite plate is processed by traditional machining, the process is cumbersome, the cost is high, and it is not conducive to mass production. Bipolar plates made of metals (aluminum, titanium, nickel, stainless steel) and their alloys (aluminum alloys, titanium alloys, etc.) solve the shortcomings of the brittleness of graphite plates and are suitable for mass production. The shortcomings are mainly poor corrosion resistance, and electrode diffusion layer. The contact resistance is large and the surface treatment must be carried out, causing the cost to rise.
膨胀石墨极板经过模压成型为带有一定流场的形状后，需要将其放入液态的热固性树脂中进行浸渍，然后树脂进入膨胀石墨极板孔隙内的树脂的固化，提高柔性石墨极板的强度同事还提升了膨胀石墨极板的气密性。After the expanded graphite plate is molded into a shape with a certain flow field, it needs to be put into a liquid thermosetting resin for impregnation, and then the resin enters the solidification of the resin in the pores of the expanded graphite plate to improve the flexibility of the flexible graphite plate. The strength colleagues also improved the air tightness of the expanded graphite plates.
现有的膨胀石墨极板主要应用的浸渍树脂为热固性树脂如聚酰亚胺树脂、丙烯酸树脂、酚醛树脂或环氧树脂等；这些树脂如酚醛树脂和环氧树脂存在着粘度过大，浸渍后的膨胀石墨极板气密性不足，而低粘度的丙烯酸树脂浸渍后的膨胀石墨板拥有良好的气密性，但是其强度较低。The main impregnating resins used for the existing expanded graphite plates are thermosetting resins such as polyimide resin, acrylic resin, phenolic resin or epoxy resin; The expanded graphite plate has insufficient air tightness, while the expanded graphite plate impregnated with low-viscosity acrylic resin has good air tightness, but its strength is low.
如专利CN201910257160.7一种燃料电池双极板的模压制备方法中的步骤：Such as the steps in the molding preparation method of the fuel cell bipolar plate of the patent CN201910257160.7:
该专利采用的树脂为聚酰亚胺树脂、丙烯酸树脂、酚醛树脂或环氧树脂。The resin used in this patent is polyimide resin, acrylic resin, phenolic resin or epoxy resin.
当前膨胀石墨板浸渍常使用丙烯酸树脂，该树脂具有粘度低，浸渍效果良好的优点，使用时将丙烯酸酯树脂与一定量的偶氮二异丁腈混合，然后浸渍出来的石墨板的抗弯强度通常在15～30MPa，抗压强度在40～50MPa，无论抗弯还是抗压强度都较低，影响极板的结构设计，同时也无法进一步制备厚度更薄的膨胀石墨双极板。At present, acrylic resin is often used for impregnation of expanded graphite sheets. This resin has the advantages of low viscosity and good impregnation effect. When using, acrylic resin is mixed with a certain amount of azobisisobutyronitrile, and then the flexural strength of the impregnated graphite sheet is Usually 15-30 MPa, compressive strength is 40-50 MPa, both flexural and compressive strengths are low, which affects the structural design of the polar plate, and at the same time, it is impossible to further prepare expanded graphite bipolar plates with a thinner thickness.
膨胀石墨极板浸渍后的强度很大程度上取决于所选用的树脂，因此，选择性能更加优异的乙烯基树脂来浸渍膨胀石墨极板，可以获得性能更好的产品。The impregnated strength of the expanded graphite plate depends to a large extent on the selected resin. Therefore, selecting a vinyl resin with better performance to impregnate the expanded graphite plate can obtain a product with better performance.
