Patent ID: 8282989

Claim:
A method for manufacturing an assembly ( 1 , 100 , 200 , 300 ) for a fuel cell comprising at least two adjacent cell components taken from a cathode ( 22 ), and anode ( 18 , 118 ), an electrolyte ( 20 ) and a sealed plate ( 24 ), said method being applied by means of successive steps consisting of: a) at least partially solidifying, by laser sintering, a powder layer (Ci) deposited beforehand so that it forms a section (Sn+1) of the assembly; and b) depositing a successive powder layer (Ci+1) on the powder layer (Ci) deposited beforehand, and at least partially solidified by laser sintering; steps a) and b) being alternately repeated until the obtained stacked sections (S 1 -Sp), made integral with each other during the carrying out of the solidification steps by laser sintering, form together the assembly comprising at least two cell components ( 18 , 118 , 20 , 22 , 24 ), characterized in that it is applied so that at least one of the obtained sections (S 1 -Sp) has at least two areas with different porosities in the main plane of said obtained section (S 1 -Sp), and at least two of the powder layers (Ci, Ci+1) have a different thickness.
