    • PURPOSE: A method for improving ion conductivity of a solid polymeric membrane having conductivity lower than that of a liquid electrolyte is provided to obtain a high conductivity sufficient to be used in fuel cells, secondary batteries and capacitors. CONSTITUTION: The method for improving ion conductivity of a polymeric electrolyte membrane for use in a polymeric electrolyte-based fuel cell comprises applying a strong electric field to a membrane having an electric moment therein from outside to change the molecular orientation inside of the membrane, through a poling process. The electric field has strength of 5-20 kV/cm and the poling process is carried out for 30-90 minutes.
    • 目的:提供一种提高电导率低于液体电解质的固体聚合物膜的离子传导性的方法,以获得足以用于燃料电池,二次电池和电容器中的高电导率。 构成:用于改进用于聚合物电解质基燃料电池的聚合物电解质膜的离子传导性的方法包括从外部向其中具有电力矩的膜施加强电场以改变膜内部的分子取向,通过 一个极化过程。 电场强度为5-20kV / cm,极化过程为30-90分钟。

    • PURPOSE: A process for producing a fermented seaweed feed is provided, therefore it is possible to effectively use the seaweed for producing a high functional feed and improving meat quality. CONSTITUTION: The process for producing a fermented seaweed feed comprises the steps of: collecting seaweeds with roots, stems and sporophyll; drying them until they have water content of 65 to 70% and dried weight of 30 to 35%; slicing the dried seaweeds into a size of 1cm; inserting the sliced seaweeds into a tank; spraying a medium, in which seaweed fermenting microorganisms are cultured, thereinto; pressing and removing air from the tank to make the tank vacuum; fermenting the seaweeds for 4 to 7 days; and packaging them under vacuum or nitrogen condition.
    • 目的:提供生产发酵海藻饲料的方法,因此可以有效地利用海草来生产高功能饲料并提高肉质。 构成:生产发酵海藻饲料的方法包括以下步骤:用根,茎和孢子叶收集海藻; 干燥至含水量为65〜70%,干燥重量为30〜35%。 将干燥的海藻切成1厘米的大小; 将切片的海藻插入罐中; 喷洒培养海藻发酵微生物的培养基; 从罐中压出并排出空气使罐体真空; 发酵海藻4〜7天; 并在真空或氮气条件下包装。
