Description
Technical Field
The invention relates to the technical field of fuel cells, in particular to a gas-liquid separation device with visible airflow.
Background
In the fuel cell, both hydrogen and oxygen as reactants are colorless gases. Therefore, in the parts and the pipelines of the air and hydrogen subsystem, even if a transparent window is added, the gas flow state is difficult to directly observe.
In addition, the flow state of the gas-liquid two-phase flow is also difficult to capture. Taking the hydrogen side water diversion as an example, in order to improve the hydrogen utilization rate, the fuel cell generally adopts a hydrogen reflux mode, namely, a pile-out gas-liquid mixture is mixed with fresh hydrogen from a hydrogen bottle under the driving of a circulating pump or an ejector, and the mixture is supplied to a pile reaction again. The gas-liquid mixture from the pile comprises unreacted hydrogen, water vapor, nitrogen and liquid water, and the density difference between the liquid water and the gas is huge, so that a gas channel is blocked after the liquid water enters the pile, and the performance of the pile is deteriorated. Therefore, a gas-liquid separator is required to be provided in the stack outlet line to separate a large amount of liquid water and discharge the water.
Compared with a centrifugal type gas-liquid separator and a filter element type gas-liquid separator, the baffle type gas-liquid separator has the advantages of small flow resistance, high integration level and simple processing, but because the liquid drops and the cover plate are colorless, the cover plate surface is generally frosted, the definition is reduced, and therefore the gas-liquid change is difficult to clearly see.
