Claim 0:
1. A gaseous fuel-air mixer comprising:
an outer shell comprising:
an air intake that defines an air intake center axis and is configured to receive air, the air intake having an air outlet, and
a fuel intake having a fuel inlet centered on a fuel intake center axis that is configured to receive fuel;

an inner shell comprising an inner shell intake that is configured to separately receive the air from the air outlet and the fuel from the fuel intake and to provide a gaseous fuel-air mixture, the inner shell cooperating with the outer shell to define a fuel intake collecting chamber that is configured to receive the fuel from the fuel inlet and a fuel intake concentrating chamber that is configured to receive the fuel from the fuel intake collecting chamber and provide the fuel to the inner shell intake; and
a fuel chamber rib that is coupled to at least one of the outer shell or the inner shell, the fuel chamber rib disposed along the fuel intake center axis within at least one of the fuel intake collecting chamber or the fuel intake concentrating chamber,
wherein the fuel chamber rib extends in a direction parallel to the air intake center axis defining a first passage and a second passage of at least one of the fuel intake collecting chamber or the fuel intake concentrating chamber.
