H15C15 采用更薄的基材设计，在保持较低穿透电阻的同时，能够满足高压紧、高电流密度及长寿命运行要求，因此适用于重型商用车、公交车、船舶及轨道交通等应用。
建议始终将 MPL 一侧朝向催化层。
这样可以：
可以。
对于 CO₂ 电还原、部分电解水实验及部分燃料电池研究，可直接将催化剂喷涂于 MPL 表面，制备气体扩散电极（GDE）。
建议喷涂在 MPL 面。
MPL 可提供更均匀的表面，有利于催化层附着和电流分布。
一般无需清洗。
如需去除表面灰尘，可采用：
避免使用强氧化剂、浓酸、浓碱等腐蚀性介质。
不建议。
长时间超声可能导致：
如确需分散表面污染物，建议采用低功率水浴超声，时间控制在 5–10 分钟 内。
正常使用条件下不会。
若出现脱落，通常与以下因素有关：
少量表面微粉属于正常现象，不影响使用。
若出现明显大片脱落，则应检查是否存在运输挤压、超声处理或安装过程中受到外力损伤。
科研测试中可根据实际情况重复使用，但需确认：
对于正式性能测试，建议使用新的 GDL，以确保实验重复性。
不是。
压缩过大会：
一般建议压缩率控制在 20%–30%。
不建议。
虽然碳纸具有一定柔韧性，但反复折叠可能导致：
建议平放或采用卷绕方式运输（卷绕半径应足够大）。
建议：
兼容绝大多数燃料电池催化剂，包括：
可搭配多种离聚物使用，例如：
通常不需要。
H15 系列出厂即可使用，无需酸洗、烧结或等离子处理。
导电性能受以下因素共同影响：
因此，不同型号会针对不同应用进行优化设计。
这是由于不同产品采用了不同的测试方法。
由于测试标准不同，两者不能直接换算，应结合官方测试方法进行比较。
