According to the company, its fuel cell stack technology incorporates uncoated metal plates that provide superior resistance to shock and vibration, and open flow field architecture for high power density and efficiency.
The bipolar plates with special flow field patterns represent one important component of a PEM fuel cell.
This method performs well on different urban scenarios when the camera or objects are either moving or static; (2) A multi-level pyramidal architecture of down-sampled images is built to deal with different displacements of objects moving at different speed and location from the vehicle; (3) The inclusion of a penalization function and a filtering step to make the system more robust against outliers in the final flow field; (4) We evaluate the performance of our approach using image sequences from the Daimler Benchmark dataset [1] to estimate motion in real urban environments.
Fuel Cell performance is impacted by the design of the "flow field," which describes the means by which reactant and waste gases move through the bipolar plates.
The fiber diameter of melt blowing nonwovens is strongly affected by the air drawing model and air jet flow field model.
However, very little research has been carried out on the influence on the engine flow field by the valve lift curve of Miller cycles.
The expansion status is significant to the flow field, which is substantial to abrasive acceleration and abrasive velocity impacting the material [17].
Based on the hypersonic flow field data obtained in the repeatable laboratory simulations using ballistic range [11] or plasma wind tunnel [12], more practical physical models of hypersonic flow field can be established using the CFD technique [17].
Obviously, the effect of distributed roughness on the flow field is more complicated.
Therefore, studying the internal flow field of the partially pressured injection tool is necessary [1, 2].
The coupling of the electric field force, the flow field, the temperature field and the ion motion within the microchannel, the electroosmotic flow, electrophoresis, induced electroosmotic flow, and other electrical phenomena can be used to achieve microfluidic (microparticle) transport and control [5, 6].
