Why is a high-precision differential pressure sensor necessary for hydrogen production through electrolysis?

Why is a high-precision differential pressure sensor necessary for hydrogen production through electrolysis?

It is related to back pressure control under high pressure!

As attention focuses on hydrogen, which is considered a pillar of the future of energy, the importance of electrolyzers that decompose water into hydrogen is increasingly rising. In a proton exchange membrane (PEM) electrolyzer, water enters one side of the device, and hydrogen passes through a permeable membrane to the opposite side due to the electric current, resulting in the decomposition of water into oxygen and hydrogen. Since hydrogen is often stored at high pressure after electrolysis, it is considered preferable to operate the electrolyzer at high pressure as well, as this can eliminate the need for additional compression processes. Therefore, it is necessary to control the pressure of the oxygen and hydrogen generated in the electrolyzer, and even if this can be achieved through back pressure control, it is essential to minimize the pressure difference between the two flows to avoid mechanical stress on the electrolyzer's membrane. For example, what should be done if the pressure difference between the oxygen side and the hydrogen side in a high-pressure electrolyzer is low, ranging from 1 to 10 kPa (which is the maximum pressure difference that the membrane can handle)? What if a pressure measurement accuracy of <0.1% FS is required? This is where Keller's differential pressure sensor PD-39X comes into play. The PD-39X is equipped with two absolute pressure sensors, excels in pressure resistance on one side, and can achieve an accuracy of 0.1% FS.
