                      cells (PEMEC) can lead to reduced usable hydrogen output,
                      shortened lifespan, and interruptions in operation due to
                      safety concerns. Extensive studies have explored the
                      crossover mechanism under various operating conditions using
                      different setups. In this study, we demonstrate a setup that
                      is capable of quantifying hydrogen and oxygen permeability
                      of dry and wet membranes, as well as catalyst coated
                      membranes; i.e. membrane electrode assemblies (MEAs). We
                      monitored the hydrogen and oxygen permeabilities of
                      Nafion™ N115, N117 and NR212 membranes, respectively, and
                      studied the effect of catalyst coating on hydrogen
                      permeability of the membrane. The impact of conditioning on
                      N115-based MEAs in a fully hydrated state was investigated.
                      To realize this, MEAs were subjected to various conditioning
                      protocols; break-in (applied current), in situ vs ex situ
                      pre-treatment (water exposure), and elevated vs lowered
                      temperature pre-treatment, which revealed a significant
                      influence on hydrogen permeability.},
