15. The fuel reformulation system of claim 1 , wherein the at least one screen member comprises a stack of screen members.
16. The fuel reformulation system of claim 1 , wherein the at least one screen member comprises a mesh of short contact time elements.
17. The fuel reformulation system of claim 1 , wherein the at least one screen member comprises a wire mesh comprising the catalytic material.
18. The fuel reformulation system of claim 1 , wherein the at least one screen member comprises a wire mesh coated with the catalytic material.
19. A fuel reformulation system, comprising:
a fuel source;
an annular body located within an engine and comprising:
an air inlet upstream of an outlet of the fuel source and configured to receive air separate from fuel from the fuel source;
a mixing section downstream of the air inlet and the outlet of the fuel source, the mixing section positioned and configured and positioned to produce a fuel and air mixture from the air and the fuel; and
at least one screen member downstream of the mixing section and comprising a catalytic material positioned and formulated to convert a portion of the fuel and air mixture into hydrogen gas; and
