Things To Note When Transporting Polymer Membranes For Fuel Cells:
Laws and Regulations: Ensure that the transportation process complies with all relevant laws and regulations, including export and import laws and regulations, and ensure that all necessary documents and permits are in place.
Tracking and Communication: Use a tracking system to monitor the status of equipment transportation, maintain good communication with the transportation company, and keep abreast of the transportation progress and any possible problems.
Arrival Inspection: Check the equipment immediately after arrival to confirm that the equipment is in good condition and the quantity is correct. If any problems are found, contact the transportation company in time and record the relevant situation.
Storage: Before the final installation of the equipment, ensure that it is stored in a dry and safe environment, avoid direct storage on the ground to prevent moisture or other potential damage.
Notes Of Polymer Electrolyte Membranes:
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).
