摘要
采用湿法造纸技术制备质子交换膜燃料电池电极扩散层专用碳纸材料,考察了影响专用碳纸性能的主要因素。研究结果表明：分散剂、粘合剂和纤维长度等对碳纸物性具有较大影响。以3M的NaOH处理碳纸的基体材料,控制打浆度20°SR,按比例加入自制功能性分散剂,在优化工艺条件下,制备的碳纸物性基本和日本东丽公司产品(Toray碳纸)物性相同。以自制的碳纸和Toray碳纸为电极扩散层基体材料组装成电池,放电性能测试表明,自制碳纸是一种较为理想的燃料电池电极扩散层基体材料。
Special carbon paper materials for proton exchange membrane fuel cells were prepared by wet papermaking technique. The effects affecting the performance of special carbon paper were investigated. It was shown that dispersant, bond and length of fiber have great effects on the characteristics of carbon paper. Under the optimized technical conditions, the raw materials of carbon paper were processed by 3M NaOH solution. The beating degree of the pulp is 20°. Homemade functional dispersant is added in appropriate proportion. The properties of carbon paper were close to or better than that of Toray carbon paper. The discharge performance of cells , assembled by the raw materials of electrode diffu- sion layer with homemade carbon paper and Toray carbon paper, were determined. It was found that homemade carbon paper is the perfect raw material of electrode diffusion layer in the electrode diffusion layer of fuel cells.
