Test whether the pressure is equilibrium 05.05.2023

If the water level sensors are in the parallel level throughout the test period, we have come to a solution to the problem of pressure difference within a single cell. Now we can replace the membrane with Nafion.
But if the water level sensors aren't in the parallel level throughout the test period, this means that there is a problem with suffocation (closed) in one of the condenser tubes.

Goal:

In the previous test, we had a problem with the pressure balance between the two half-cells, and to resolve this problem, we suggested placing flashback arrestor at the oxygen gas outlet. The aim of this test is to ensure the correctness of the pressure balance between the two half-cells.

Expected result:

In case of equilibrium between the two half-cells, the level sensor pointer for each half-cell (water level parallels between the cathodic half-cell and the anodic half-cell).

If there is a pressure difference between the two-level sensors, we should notice a difference in the level of the solution at the two sensors.

Operation Steps:

00008: A simple test of an Electrolysis system -Case add water manually-

Data collected during test:

   ⚠️Note:

      1️⃣The intensity (I) measures the AC, while the voltage (V) measures the DC.

      2️⃣ The inlet of O₂ condenser is too warm than inlet of H₂ condenser.

Result view:

Level sensors: on the left side, the level sensor placed on the anodic half-cell. On the right side, the level sensor placed on cathodic half-cell.

Conclusion:

At the end of the test, we found that the water level in the sensor was almost identical. Which means that the pressure differential problem has been preliminarily resolved.
