| 摘要 |
The invention relates to a membrane-electrode unit comprising at least one membrane, at least two electrode layers, and at least one barrier junction that contains at least one catalytically active species and/or at least one adsorbent material, the barrier junction not being electronically conducting when a catalytically active species is provided. Also disclosed are the use of such a barrier junction in a membrane-electrode unit and in a fuel cell as well as a gas diffusion electrode and a fuel cell containing such a membrane-electrode unit. ® KIPO & WIPO 2009 |
