Corrosion behaviour of nitrided ferritic stainless steels for use in solid oxide fuel cell devices

open access: yes, 2020
Plasma nitriding was applied to ferritic stainless steel substrates to improve their performances as interconnects for solid oxide fuel cell devices. The samples underwent electrical conductivity test and SEM/EDS, TEM/EDS, environmental-SEM analyses. The

Transient non-isothermal model of a polymer electrolyte fuel cell

open access: yes, 2007
In this paper we present a one-dimensional transient model for the membrane electrode assembly of a polymer-electrolyte fuel cell. In earlier work we established a framework to describe the water balance in a steady-state, non-isothermal cathode model ...

First principles studies of the size and shape effects on reactivity of the Se modified Ru nanoparticles

open access: yes, 2012
We present here the results of our density-functional-theory-based calculations of the electronic and geometric structures and energetics of Se and O adsorption on Ru 93- and 105-atom nanoparticles. These studies have been inspired by the fact that Se/Ru
