Carbon paper for proton exchange membrane hydrogen fuel cell and preparation method of carbon paper
The invention belongs to the technical field of preparation methods of conductive materials, and particularly relates to carbon paper for a proton exchange membrane hydrogen fuel cell and a preparation method of the carbon paper. According to the carbon paper for the proton exchange membrane hydrogen fuel cell, the problem that carbon fibers in carbon paper are difficult to uniformly distribute can be solved, and the conductivity of the carbon paper is improved. The preparation method comprises the preparation steps: putting a mixture of a dispersing agent 1 and carbonized fibers into water, and pulping to uniformly disperse carbonized fibers to form a suspension; adding a dispersing agent 2 into the suspension, and continuously stirring to uniformly disperse the carbonized fibers to forma uniform suspension; carrying out papermaking on the suspension by adopting a wet papermaking method; dipping paper made by the wet papermaking method with a binder; curing the paper dipped with thebinder; carbonizing the obtained paper to obtain the carbon paper for the proton exchange membrane hydrogen fuel cell.
本发明属于导电性材料制备方法技术领域，具体涉及一种质子交换膜氢燃料电池用炭纸及制备方法。所述质子交换膜氢燃料电池用炭纸，可解决炭纸中碳纤维难以均匀分布的问题，提高炭纸的导电性。其制备步骤为：将分散剂1、炭化纤维的混合物放入水中，打浆使得炭化纤维丝分散均匀，形成悬浮液；向悬浮液中加入分散剂2，继续搅拌使炭化纤维分散均匀，形成均一的悬浮液；采用湿法抄纸方法将悬浮液进行抄纸；将湿法抄纸抄成的纸用粘结剂进行浸渍；将浸渍粘结剂的纸进行固化；将得到的纸炭化处理，得到质子交换膜氢燃料电池用炭纸。
