نویسندگان
چکیده
A dynamic model for the concentration admittance of a polymer electrolyte fuel cell is presented. The takes into account oxygen transport in cathode channel, gas diffusion layer, and catalyst layer. An analytical solution derived. We observe that at air channel outlet not affected by faradaic reactions, it contains information on coefficients cell. measured can be fitted using formula obtained this work to extract coefficients. Practical methods measuring are proposed.

investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Transient non-isothermal model of a polymer electrolyte fuel cell
In this paper we present a one-dimensional transient model for the membrane electrode assembly of a polymer-electrolyte fuel cell. In earlier work e established a framework to describe the water balance in a steady-state, non-isothermal cathode model that explicitly included an agglomerate atalyst layer component. This paper extends that work in several directions, explicitly incorporating comp...

متن کاملEffect of CO in the reformatted fuel on the performance of Polymer Electrolyte Membrane (PEM) fuel cell
There are several obstacles to the commercialization of PEM fuel cells. One of the reasons is that the presence of carbon monoxide (CO) in the reformatted fuel, even at a very small scale, decreases the fuel cell performance. The aim of this paper is to investigate the effect of CO in reformatted fuel on PEM fuel cell performance. For this purpose, a steady state, one-dimensional and non-isoth...
