... are composed of H 2 , CO, CO 2 , CH 4 , and H 2 O. The relative concentration of each of the species of this mixed gas has an impact on the efficiency of the MC-DCFC. How the relative concentration of these gases in this electrolyte can impact the performance parameters of the MC-DCFC is systematically...

In this study, Ni 2...

..., particle size, composition, structure, and electrochemical performance. According to the test results, when the initial mass concentration of Fe 3+ in the reaction solution is 2%, the amount of N and S impurity is merely 19 and 27 ppm, respectively. In the meantime, particle size is small, with a range...

...Dustin Lee; Jing-Kai Lin; Chun-Huang Tsai; Szu-Han Wu; Yung-Neng Cheng; Ruey-Yi Lee The effects of isothermally long-term and thermal cycling tests on the performance of an ASC type commercial solid oxide fuel cell (SOFC) have been investigated. For the long-term test, the cells were tested over...

... emissions, reduce fossil fuel dependency and increase energy efficiency. Even though great progress has been made, long-term stability and durability is still an issue. The contamination ion plays an important role on the electrical performance of PEM fuel cell. This paper investigates the effect of Mg 2...

..., simplicity to manufacture into stampable bipolar plates, and its light weight. Our goal is to obtain a smaller and lighter weight single fuel cell is to sinter titanium with a corrosion resistant material. Iridium oxide (IrO 2 ) was investigated. The cell performance of the iridium oxide-sintered bipolar...

... membrane, and membrane electrode structure (MEA) are the same as our previous work, as described in Ref. [ 1 ]. This work focuses on the structural enhancement to the anode side of the fuel cell to improve fuel cell performance and fuel efficiency with high concentration methanol, up to 20 M. Similar...

...Zhenwei Wang; Masashi Mori The steam electrolysis performance of a Ni-based electrode-supported tubular cell with a Sc 2 O 3 -stabilized ZrO 2 electrolyte was evaluated at 650°C for various concentrations of H 2 and O 2 in the supply gases. It was found that an increase in the concentration...

...Katie S. Howe; Kevin Kendall The transient performance of microtubular solid oxide fuel cells was investigated, with promising results. It was found that a single cell can take less than half a second to adjust to load changes, even when the change steps across the majority of the cell’s range...
