WO 2008116604 A1 UPAB: 20081126 NOVELTY - The cell has a membrane-electrode unit that is made of an ion-conducting membrane with catalyst layers. The catalyst layers are arranged on opposing sides of the ion-conducting membrane and serve as cathode and anode. The membrane-electrode unit has adjacent regions with different diffusion transport for feeds and/or products. One of the catalyst layers in a region with lower diffusion transport exhibits a higher diffusion barrier than the catalyst layer in the region with higher diffusion transport. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for production a fuel cell. USE - Fuel cell e.g. hydrogen-polymer-electrolyte-membrane fuel cell (PEMFC), for directly converting a chemical energy into an electrical energy. ADVANTAGE - The fuel cell can be manufactured in an easy and cost effective manner and can be handled in easy manner
