摘要： The present disclosure generally relates to systems and methods of purifying hydrogen, comprising humidifying, oxygenating, and purifying an impure gas stream to produce hydrogen in an electrochemical pump stack. The purified hydrogen is segregated and dispelled from the electrochemical pump stack.

摘要： A fuel cell including a catalyst layer configured to generate liquid water in response to a reactant being in contact therewith. The fuel cell includes a microporous layer having a first region with a first pore size and a second region disposed adjacent to the first region having a second pore size. The first pore size being greater than the second pore size. The microporous layer being configured to transfer the liquid water away from the catalyst layer, such that the liquid water from the catalyst layer enters the first region in response to a capillary pressure of the liquid water being greater than a first capillary pressure. The liquid water enters the second region in response to a capillary pressure of the liquid water being greater than a second capillary pressure. The first capillary pressure being different from the second capillary pressure.
