A Discussion About Two-Phase Flow Pressure Drop in Proton Exchange Membrane Fuel Cells

A proton exchange membrane (PEM) fuel cell produces water during its operation which results in a liquid-gas two-phase flow within its flow channels. Because the length scales associated with flow channels are small, the two-phase flow in PEM fuel cell is ...

Influence of the bias-dependent emission zone on exciton quenching and OLED efficiency

Beat Ruhstaller, Markus Regnat

We present an electro-optical model of a three-layer phosphorescent OLED which accurately describes the measured current efficiency and transient electroluminescence decay for different biases. Central findings are a bias-dependent emission zone, which inf ...
