Abstract (300 words maximum)
Clean energy is rapidly becoming the primary energy source for big businesses. The study of lanthanum strontium manganate (LSM) and chromium (Cr) degradation will prove useful for future endeavors with energy storage system longevity and efficiency. Chromium is present in stainless-steel, which is used in industry as, amongst other things, a cost-efficient option for mass manufacturing of battery and electrical housings. Under heat, chromium evaporates in small amounts from the stainless-steel components, which interferes with the efficiency of energy transfer. By utilizing an yttria-stabilized zirconia (YSZ) electrode with LSM, we replicate a small-scale, real-world energy conversion system using heat and oxygen as catalysts. Sample cells, both with and without Cr, had a YSZ electrode and a thin, porous film of LSM. Exposing each cell to temperatures up to 800°C over a period of roughly 10-11 days each yielded data for Nyquist plots and current vs time graphs that demonstrate effects of Cr on the efficiency of the fuel cell under realistic conditions. Our research centers upon the presence of Chromium in electrical systems, and its deteriorating effects on transfer systems over predetermined time and temperature cycles.
