The present invention proposes a micro-tubular solid oxide fuel cell arrangement comprising at least two micro-tubular elements (10, 10'), the micro-tubular elements (10, 10') comprising a tubular inner electrode (14), covered on its outer surface with an electrolyte (16), the electrolyte (16) being covered on its outer surface with a tubular outer electrode (18); and a connection element arranged between the micro-tubular elements (10, 10') for connecting one end of one micro-tubular element (10) to one end of the other micro-tubular element (10'). According to an important aspect of the invention, the micro-tubular element (10, 10') comprises a first end portion (20) with an inner cone (32) arranged in the tubular inner electrode (14) and a second end portion (26) with an outer cone (30) arranged in the tubular outer electrode (18). The connection element comprises a metallic interconnector plate (12, 12') having a first side (36) and an opposite second side (38). The interconnector plate (12, 12') is provided with at least one hole (34); a first metallic connector (40) on the first side (36) and arranged around the hole (34) and a second metallic connector (42) on the second side (38) and arranged around the hole (34). The first metallic connector (40) has a conical shape with a cross-section narrowing in a direction away from the interconnector plate (12, 12'), the first metallic connector (40) being dimensioned and arranged for contacting the first end portion (20) of one of the micro-tubular elements (10). The second metallic connector (42) has a conical shape with a cross-section growing in a direction away from the interconnector plate (12, 12'), the second metallic connector (42) being dimensioned and arranged for contacting the second end portion (26) of another one of the micro-tubular elements (10'). |
