| 摘要 |
The invention relates to a membrane electrode unit for a fuel cell, comprising an optionally catalyst-coated anode, an optionally catalyst-coated cathode and a proton conductor located between said anode and said cathode. The proton conductor consists of a microfibre-fleece material which has been impregnated with an electrolyte to the point of saturation. The fleece material is chemically inert in relation to the electrolyte at temperatures of up to +200 DEG C and in oxidising and reducing conditions and weighs 20 to 200 g/m<2>. The thickness of the fleece is less than 1 mm and the pore volume is 65 to 92 %. |
