Abstract[English]
. The anode catalyst layer has a mean average cross-sectional thickness of ≥3.0 μm and ≤10 μm. The anode catalyst layer comprises pores having a total pore volume, wherein the pores comprise first pores having a pore diameter in a range of 50 nm to 500 nm, wherein the first pores have a pore volume of at least 30% of the total pore volume of the pores in the anode catalyst layer, as measured by mercury intrusion porosimetry.[French]
. La couche de catalyseur d'anode a une épaisseur moyenne de section transversale moyenne ≥ 3,0 µm et ≤ 10 µm. La couche de catalyseur d'anode comprend des pores ayant un volume de pores total, les pores comprenant des premiers pores ayant un diamètre de pore compris entre 50 nm et 500 nm, et le volume de pores des premiers pores représentant au moins 30 % du volume de pores total des pores dans la couche de catalyseur d'anode, tel que mesuré par porosimétrie au mercure.
