The injector ring (42) is disposed about the axis (A) at the first axial end (40a, 40b) and is configured to introduce a hydrogen and gas mixture into the combustion chamber (40). The injector ring (42) includes gas feed conduits (66) that open into a central mixing region (64), a hydrogen manifold cavity (52) that has first and second isolated compartments (54, 56), first hydrogen feed conduits (60) that extend off of the first isolated compartment (54) and open into the central mixing region (64), and second hydrogen feed conduits (62) that extend off of the second isolated compartment (56) and open into the central mixing region (64).",
