1. An assembly for a turbine engine with a flowpath, comprising:
a fuel source; and
an engine component forming a peripheral boundary of the flowpath, the engine component comprising a component internal passage, the engine component configured to receive fuel from the fuel source, the fuel flows from a downstream side towards an upstream side with respect to the flowpath, and the engine component configured to crack at least some of the fuel within the component internal passage thereby cooling the engine component and providing at least partially cracked fuel;
wherein the assembly is configured to direct the at least partially cracked fuel into the flowpath for combustion in a combustion chamber of the turbine engine, and the at least partially cracked fuel comprises H2 gas; and
wherein the engine component comprises material that at least partially forms the component internal passage, and the material comprises at least one of nickel (Ni), iron (Fe) or ruthenium (Ru).
