Embodiments are directed to composite membranes having a microporous polymer structure, and an ion exchange material forming a continuous ionomer phase within the composite membrane. The continuous ionomer phase refers to absence of any internal interfaces in a layer of ionomer or between any number of layers coatings of the ion exchange material provided on top of one another. The composite membrane exhibits a haze change of 0% or less after being subjected to a blister test procedure. No bubbles or blisters are formed on the composite membrane after the blister test procedure. A haze value of the composite membrane is between 5% and 95%, between 10% and 90% or between 20% and 85%. The composite membrane may have a thickness of more than 17 microns at 0% relative humidity.
