Evaluating Cathode Catalysts in the Polymer Electrolyte Fuel Cell
The polymer electrolyte membrane fuel cell (PEMFC) converts the chemical energy of hydrogen and oxygen (air) into usable electrical energy. At the cathode (the positive electrode), a considerable amount of platinum is generally required to catalyse the sluggish oxygen reduction reaction (ORR). This has implications regarding the cost in high-power applications, and for making a broad commercial...
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...
متن کاملFast Numerical Simulation of Two-Phase Transport Model in the Cathode of a Polymer Electrolyte Fuel Cell
In this paper, we apply streamline-diffusion and Galerkin-least-squares finite element methods for 2D steady-state two-phase model in the cathode of polymer electrolyte fuel cell (PEFC) that contains a gas channel and a gas diffusion layer (GDL). This two-phase PEFC model is typically modeled by a modified Navier-Stokes equation for the mass and momentum, with Darcy’s drag as an additional sour...
متن کاملTransient 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 کاملPolyaniline-derived Non-Precious Catalyst for the Polymer Electrolyte Fuel Cell Cathode
This paper focuses on a new polyaniline-derived non-precious cathode catalyst with high oxygen-reduction activity, verified in electrochemical and fuel cell testing. The rotating disk (RDE) onset and half-wave potential (E1⁄2) of oxygen reduction were measured at 0.90 V and 0.77 V, respectively. Rotating ring-disk electrode (RRDE) study revealed very good selectivity in the fourelectron reducti...
