Description
Translated fromChinese技术领域technical field
本发明涉及膜电极检测技术领域，具体涉及一种膜电极穿孔缺陷及涂层均匀度一体化检测装置。The invention relates to the technical field of membrane electrode detection, in particular to an integrated detection device for membrane electrode perforation defects and coating uniformity.
背景技术Background technique
离子交换膜、催化层、气体扩散层等部件构成了电化学反应的主要场所的部件-膜电极，气体扩散层被广泛使用于燃料电池、PEM电解水装置、二氧化碳还原、氨分解、电化学氢气泵等电化学装置中。通常膜电极中聚合物膜可能在生产中存在针孔、膜局部折皱，其表面催化层涂层可能存在裂纹、条纹、涂覆不均匀等问题。对于气体扩散电极型膜电极，热压装配的过程可能造成气体扩散层中碳管刺穿膜造成针孔、缺陷。Ion exchange membranes, catalytic layers, gas diffusion layers and other components constitute the main part of the electrochemical reaction - the membrane electrode, and the gas diffusion layer is widely used in fuel cells, PEM electrolysis water devices, carbon dioxide reduction, ammonia decomposition, electrochemical hydrogen In electrochemical devices such as pumps. Generally, the polymer membrane in the membrane electrode may have pinholes and local wrinkles during production, and the catalytic layer coating on the surface may have problems such as cracks, streaks, and uneven coating. For the gas diffusion electrode type membrane electrode, the hot press assembly process may cause the carbon tubes in the gas diffusion layer to penetrate the membrane and cause pinholes and defects.
现有的膜电极缺陷诊断通过肉眼检测，将样品置于发光板上用肉眼观察、评判分析表面的缺陷情况的方法相对原始、并且消耗大量的人力以及时间成本，生产效率低下，并且人工检测分辨率低，容易出现漏检，误检等情况的发生；The existing membrane electrode defect diagnosis is through visual inspection. The method of placing the sample on a luminescent plate to observe with the naked eye, judge and analyze the surface defect is relatively primitive, and consumes a lot of manpower and time costs. The production efficiency is low, and manual detection and resolution Low rate, prone to missed detection, false detection and other situations;
现有膜电极的缺陷诊断用激光测距仪测试，通过缺陷位置与标称距离值的偏差≥预设的允差值来确定缺陷，该方法不能排除是否运送过程中有褶皱造成误判断，若底部采用真空吸附保证无褶皱，则降低测试速度，提高时间成本；Existing defect diagnosis of membrane electrodes is tested with a laser rangefinder, and the defect is determined by the deviation between the defect position and the nominal distance value ≥ the preset tolerance value. The bottom adopts vacuum adsorption to ensure no wrinkles, which will reduce the test speed and increase the time cost;
检测微小缺陷时，若检测样品为离子交换膜，其为透明样品，不易观察，需要求探测仪器放大倍数、及快速精准探测，投入成本大且检测时间长，CCM型膜电极其表面为全黑色，不易观察孔洞，需下方放置发光设备，若检测膜电极，膜电极已装配气体扩散层，气体扩散层表面疏松多孔，无法判断缺陷存在与否。When detecting small defects, if the detection sample is an ion-exchange membrane, it is a transparent sample and is not easy to observe. It requires the magnification of the detection instrument and fast and accurate detection. The investment cost is large and the detection time is long. The surface of the CCM type membrane electrode is completely black. , It is not easy to observe the holes, and a light-emitting device needs to be placed below. If the membrane electrode is detected, the membrane electrode has been equipped with a gas diffusion layer. The surface of the gas diffusion layer is loose and porous, and it is impossible to judge whether the defect exists or not.
针对膜电极涂层均匀的检测在实验室级别中主要通过测厚仪，缺点：消耗大量的人力以及时间成本，人工检测分辨率低，容易出现漏检，误检等情况的发生，小型缺陷使用显微镜、扫描电镜、透射电镜等进行观察，缺点：只能单一的识别表面缺陷。The uniform detection of membrane electrode coating is mainly through the thickness gauge at the laboratory level. Disadvantages: consume a lot of manpower and time costs, low resolution of manual detection, prone to missed detection, false detection, etc., small defects use Microscope, scanning electron microscope, transmission electron microscope, etc. for observation. Disadvantage: only a single surface defect can be identified.
