“…Degradation due to CO is mainly associated with reduced free reaction sites due to its adsorption on the Pt electrode surface [6,17,21]. It is an effect that can be reversed after reconditioning of the stack [44].…”

“…Figure a shows the cell potential drops to 0 mV when a concentration of 10 vol % CO is reached, indicating severe poisoning at this point. The trend of the anode overpotentials, as determined by hydrogen pump experiments or by simulation, is added to this graph to complement the information. The reference μ for the evaluation of Δ μ was always that without CO at the OCP [see Eq.…”

“…When using hydrogen from a steam‐reforming system as the anode feed for the fuel cell, in addition to small amounts of CO, H 2 O will also be present . To account for this additional fuel component, we investigated species adsorbed during the anode reaction in the presence of both CO and water with realistic concentrations.…”

“…3 Recently, external RE systems for fuel cells with solid ion-conducting junctions based on Nafion tubing or the PBI/H 3 PO 4 polymer were published. 4,5 Here we present the design and test of an external RE system with solid junction specifically developed for pressurized electrochemical cells. The most meaningful RE to study ORR with respect to fuel cells is the RHE, which is a hydrogen electrode immersed in the same electrolyte and at 1 bar H 2 partial pressure.…”
