Moreover, a separate experiment also demonstrated that the cathode fouling could be mitigated under high current operation.
N3− on the catalysts lowered hydrogen adsorption capacity but showed superior adsorption capability for acetylene, the selectivity and conversion of the acetylene hydrogenation was negatively affected by N3− species under the current operation conditions.
Compared to previous full substrate removal methods, the self-heating effect of the GaN HEMT under high current operation is overcome because there is a thick copper thermal sinking layer in the design.
In spite of the operation with 95 vol% methanol, the MEA with multi-layer electrodes for high concentration methanol DMFCs shows a maximum power density of 35.1 mW cm−2 and maintains a high power density of 30 mW cm−2 (0.405 V) under constant current operation.
The significant improvement in the retention characteristics at 150°C under the small current operation of 80 μA by two-step forming are obtained as compared to single-step forming.
That is such measuring equipment, which is sensing and recording information during the engine current operation under the real conditions and real operational loading.
Under 20 mA injection current operation the room-temperature output power conversion efficiency and external quantum efficiency obtained by employing a micro-hole array on the top surface of the LED structure could be increased by 28.7% and 14.3%, respectively, over that of conventional broad area devices.
For polarisable electrodes under small to medium steady-state current operation, the model was capable of identifying electrodes with the best kinetic or mass transport behaviour and classifying behaviour in terms of relative performance.
Further study is needed to improve the cross-point resistive switching memory characteristics under low-current operation.
Long program/erase endurance and data retention at high temperature under low-current operation are also reported in published literature.
The data retention property could be improved under low-current operation by controlling the size of the conductive filament as well as percolation paths, while the density of oxygen vacancy is kept high enough.
