Precautions For Transporting Pem Water Electrolysis:
Stable placement: The equipment should be placed in a stable position on the transport to avoid any risk of the equipment moving or tipping over.
Appropriate transport: Choose the appropriate transport based on the size and weight of the equipment. Larger or heavier equipment may require a dedicated transport vehicle with appropriate securing devices.
Insurance: Consider purchasing transport insurance for the equipment to prevent damage to the equipment during transportation.
Notes Of Pem Water Electrolysis:
Measurements taken with membrane conditioned to 23℃.50%RH for 24h.
Conductivity measurement at 230.100%RH.
A base titration procedure measures the equivalents of sulfonic acid group in the polymer resin,thuscalculating the acid capacity or equivalent weight of the membrane.
Water content ofmembrane conditioned to 23 ℃ and 50%RH(dry weight basis).
Water uptake fiom dry membrane to conditioned in water at 100'℃ for l hour (dry weight basis).
