That hydrogen must be able to diffuse and exit the package, or it will rupture.
During operation of an aluminum electrolytic capacitor with non-solid electrolyte, gas pressure normally increases. This gas is mostly hydrogen and excess pressure is avoided by permeation of the gas through the capacitor’s seal.
