FIELD: systems and methods of diffusion gas exchange. SUBSTANCE: system of diffusion gas exchange and method consisting in use of membrane located between the first and second gas regions. The first gas region includes the first mechanism for direction of the first ambient gas in transverse direction from the first surface of membrane and in contact with it. The second gas region includes the second mechanism for direction of the second flow of ambient gas to transverse direction from the second surface of membrane and in contact with it. Membrane presents medium of diffusion gas exchange with curved passages running from the first surface of membrane to the second surface. Fraction of void volume amounts up to at least 0.2. Membrane possesses ability in fact to block transfer of particles from the first gas region to the second one to ensure in said way diffusion of gases between the first and second gas regions. EFFECT: intensive gas exchange due to diffusion, minimized energy consumption, excluded increase of pressure drop and frequent replacements of membranes. 52 cl, 22 dwg, 6 tbl, 50 ex
