Tackling Hydrogen Permeation

🌟 Such failure mechanism caused as a result of sensing membrane
🌟 Oil-filled sensors employ very thin isolation diaphragm typically with 0.025mm thickness
🌟 Hydrogen "plus" ions will escape through diaphragm with such thickness
🌟 As thickness increases (say 0.18mm) such permeation tends to stop subject to the operating temperature

Application - PEM Fuel Cell for Vehicles

🌟 MEMs-Based Bulk Silicon Piezo-Resistive Pressure Sensing
🌟 Sensors be used for measuring tank and hydrogen pressures before release into fuel cell
🌟 The one-piece 316L sensing element is capable to pass all standards for hydrogen pressure cycles and burst pressure requirements.
🌟 Meet environmental conditions such as high pressure wash-down, salt water submersion, dust conditions, shock and vibration.
🌟 Electrical conditions simulated for up to 300V/m of EMI protection.
