A reformer module (10) comprises a hollow support member (12) having at least one passage (14) extending longitudinally therethrough. The hollow support member (14) has an external surface (20), a barrier layer (22) arranged on at least a portion of the external surface (20) of the hollow support member (12), a catalyst layer (24) arranged on the barrier layer (22) and a sealing layer (26) arranged on the catalyst layer (24) and the external surface (20) of the hollow support member (12) other than the at least a portion of the external surface of the hollow support member (12). By providing the barrier layer (22) and the catalyst layer (24) on the exterior surface (20) of the hollow support member (12), the distribution of the barrier layer (22) and/or the catalyst layer (24) may be more precisely controlled and thus a non- uniform distribution of barrier layer (22) and/or catalyst layer (24) may be achieved.

L'invention concerne un module de reformeur (10) comprenant un élément de support creux (12) possédant au moins un passage (14) s'étendant longitudinalement à travers cet élément. Cet élément de support creux (12) possède une surface extérieure (20), une couche barrière (22) placée sur au moins une partie de la surface extérieure (20) de l'élément de support creux (12), une couche de catalyseur (24) placée sur la couche barrière (22) et une couche d'étanchéité (26) placée sur la couche de catalyseur (24) et la surface extérieure (20) de l'élément de support creux (12), ailleurs que sur la partie comprenant la couche barrière. Etant donnée que la couche barrière (22) et la couche de catalyseur (24) sont situées sur la surface extérieure (20) de l'élément de support creux (12), la distribution de la couche barrière (22) et/ou de la couche de catalyseur (24) peut être plus précisément commandée et ainsi une distribution non uniforme de la couche barrière (22) et/ou de la couche de catalyseur (24) peut être obtenue.
