查询词典 cathode-ray tube

The invention provides a method for preparing a tube-shaped cathode of a direct methanol fuel cell, belonging to the fuel cell field and comprising the steps of: dispensing a single solution for gel injection molding at first, then adding a mesophase bituminous coal micro ball into the single solution and stirring evenly to obtain stable slurry, then casting the slurry into a die, preserving heat until the single solution reacts with a cross-linker completely to obtain a carbon-biscuit, after drying and sintering the biscuit in vacuum, preparing a diffusion layer and a catalyst layer on the surface by dipping process, and then coating polyester electrolyte membrane with a burette, rolling the carbon on a warm table to solidify the electrolyte membrane.

一种制备直接醇燃料电池管状阴极的方法，属于燃料电池领域。本发明首先配制凝胶注模用单体溶液，之后将中间相沥青炭微球加入到单体溶液中，搅拌均匀得到稳定的浆料，然后将浆料浇注到模具中，保温至单体与交联剂完全反应，得到炭管素坯，将素坯烘干、真空烧结后，在其表面采用浸渍工艺制备扩散层、催化剂层，然后采用滴管涂覆聚合物电解质膜，在加热台上对炭管进行滚压，使电解质膜固化。
