Abstract:
(EN) A solid polymer-type fuel cell catalyst carrier which satisfies the following requirements (A), (B), (C), and (D), a method for manufacturing the same, a catalyst layer for a solid polymer-type fuel cell, and a fuel cell. (A) The specific surface area according to a BET analysis of a nitrogen adsorption isotherm is 450 to 1500 m2/g. (B) A nitrogen adsorption-desorption isotherm forms a hysteresis loop in a range of relative pressure P/P0 = more than 0.47 to 0.90, where the area ΔS0.47-0.9 of the hysteresis loop is 1 to 35 mL/g. (C) The relative pressure Pclose/P0 at which the hysteresis loop is closed is more than 0.47 to 0.70. (D) The half-value width of G-band detected in a range of 1500 to 1700 cm-1 according to Raman spectrometry is 45 to 75 cm-1.

(A) La surface spécifique selon une analyse BET d'une isotherme d'adsorption d'azote est de 450 à 1500 m2/g. (B) Une isotherme d'adsorption-désorption d'azote forme un cycle d'hystérésis dans une plage de pression relative P/P0 = de plus de 0,47 à 0,90 , la surface ΔS0,47-0,9 du cycle d'hystérésis étant de 1 à 35 ml/g. (C) La pression relative Pproche/P0 à laquelle le cycle d'hystérésis est fermé est de plus de 0,47 à 0,70. (D) La largeur de demi-valeur de la bande G détectée dans une plage de 1 500 à 1 700 cm-1 selon la spectrométrie Raman est de 45 à 75 cm-1.
