  "textContent": "The invention relates to Membrane Electrode Assemblies (\"MEAs\") for solid-polymer-electrolyte proton-conducting membrane fuel cells (\"PEM-FCs\") having better performance and improved durability, in particular when operated under severe electrochemical conditions such as fuel starvation and start-up/shut-down cycling. [0002] The MEAs are characterized in that at least one of its two electrode layers (EL1 and/or EL2) contains a first electrocatalyst (EC1) comprising an iridium oxide component in combination with at least one other inorganic oxide component and a second electrocatalyst (EC2/EC2'), which is free from iridium. Preferably, an iridium oxide/titania catalyst is employed as EC 1. [0003] The MEAs reveal better performance, in particular when operated under severe operating conditions such as fuel starvation and start-up/shut-down cycling.",
