The invention relates to a high-temperature solid oxide fuel cell having a tubular structure with an anode supporting electrode and is intended to create a single tubular cell having an effective cathode current collector. The cathode current collector is made of a material based on a metal powder and/or a metal oxide powder and/or an intermetallic compound powder, said cathode current collector being applied in the form of a strip onto the surface of the outer side of the cathode electrode or onto the inner side of the cathode electrode facing the electrolyte, the current collector is non-separably attached to the surface on which it is applied and has a porous structure having a volume porosity of 10-70%. The claimed method for forming a cathode current collector of a tubular battery comprises preparing a composition based on a powder of a metal powder and/or a metal oxide powder and/or an intermetallic compound having a particle size of 0.5-50 [mu] m, the composition is applied in the form of a strip to a
