摘要:
A fuel cell stack includes a plurality of fuel cells, a plurality of interconnects and a multi-material seal comprising a first seal material and a second seal material, where the second seal material first forms an effective seal at a higher temperature than the first seal material.
摘要:
A fuel cell system comprises at least one fuel cell stack, a CPOX reactor, and a conduit for providing a fuel stream to the at least one fuel cell stack through the CPOX reactor during both a start up and a steady state modes of operation of the system.
摘要:
A fuel cell system includes a fuel cell stack, at least one catalytic reactor and at least one venturi. The venturi is fluidly connected to at least one catalytic reactor.
摘要:
A method of operating a fuel cell system includes flowing a liquid fuel and optionally liquid water in sufficient proximity to a CPOX reactor such that heat from the CPOX reactor is used to vaporize the liquid fuel and optionally the liquid water. The fuel is then provided from the CPOX reactor to a fuel cell stack.
摘要:
A method of operating a fuel cell system includes introducing a fuel mixture comprising hydrogen, fuel, and steam at a fuel inlet of the fuel cell system, and operating the fuel cell system to generate electricity. A ratio of hydrogen to carbon from fuel (H2:Cfuel) in the fuel mixture is within a range of 0.25:1 to 3:1, inclusive; and a ratio of steam to carbon (S:C) in the fuel mixture is less than 2:1.
摘要:
A fuel cell system includes a fuel cell stack, a heavy hydrocarbon fuel source, and a fractionator configured to separate light ends from heavy ends of a heavy hydrocarbon fuel provided from the heavy hydrocarbon fuel source.
