WebThe upper flammability limit of hydrogen in oxygen is 94%. Meaning 6% oxygen on your cathode side would be just as explosive, so the same safety considerations should apply in that regard. That said, hydrogen will generally diffuse through seals far more easily than oxygen, so depending on electrolyzer design, it may not be deemed necessary to … WebBoth have auto-ignition temperatures over 1,000°F, much higher than the auto-ignition temperature of gasoline vapor, as shown in Figure 2.
