求问一些基本问题,懂燃料电池的近来?1.Determination of the volumetric activity at 0.8 ViR-free. Whereas A g ? 1 (mass activity) is an acceptable unit for comparing the catalytic activity of non-precious metal catalysts, the preferred units by the US DOE is A cm ? 3cathode (volumetric activity)30. In addition, the US DOE has defined targets of volumetric activity for non-PGM catalysts for ORR at 0.8 ViR-free under the following reference conditions: 80 °C fuel cell temperature, 1 bar absolute pressure for H2 and O2 (excluding water vapour pressure) and 100% relative humidity。这句话怎么理解呢,特别是 0.8 ViR-free ,IR-free是什么意思呢 2.类似的关于OER 测试 时,会讲到 All LSV and CV curves are iR-corrected.这里的iR-corrected是什么意思,怎么做到的呢?查看更多3个回答 . 1人已关注
