Life Cycle Assessment of microtubular solid oxide fuel cell based auxiliary power unit systems for recreational vehicles

Results highlighted that the replacement of silver wires by the lanthanum chromium material could reduce significantly the non-fossil Abiotic Depletion Potential impact (88% reduction) and the Marine Toxicity Potential impact (18% reduction). For cutting down the GWP and the primary energy impacts it should be applied a global reduction of the energy consumed in the manufacturing and an improving in the system efficiency.
