Cathodes with MnO

Songbo WEI, He LIU, Ran WEI, Lin CHEN

Frontiers in Energy 2019, Volume 13, Issue 1,   Pages 9-15 doi: 10.1007/s11708-019-0611-5

Abstract: A series of cathodes with MnO catalysts of metal fuel battery were prepared.The cathodes were also dried with the temperature of 90°C, 120°C and 150°C.Besides, the microstructures of the cathodes and discharging performance were investigated.

Abstract:

Usage of a multiple-arcs system has significantly improved process stability and coating properties in air plasma spraying. However, there are still demands on understanding and controlling the physical process to determine process conditions for reproducible coating quality and homogeneity of coating microstructure. The main goal of this work is the application of numerical simulation for the prediction of the temperature profiles at the torch outlet for real process conditions. Behaviour of the gas flow and electric arcs were described in a three-dimensional numerical model. The calculated results showed the characteristic triangular temperature distribution at the torch nozzle outlet caused by three electric arcs. These results were compared with experimentally determined temperature distributions, which were obtained with specially developed computed tomography equipment for reconstructing the emissivity and temperature distribution of the plasma jet close to the torch exit. The calculated results related to temperature values and contours were verified for the most process parameters with experimental ones.
