Optimization of Fuel Cell Performance Using Computational Fluid Dynamics.

A low cost bipolar plate materials with a high fuel cell performance is important for the establishment of Proton Exchange Membrane (PEM ) fuel cells into the competitive world market. In this research, the effect of different bipolar plates material such as Aluminum (Al), Copper (Cu), and Stainless Steel (SS) of a single stack of proton exchange membrane (PEM) fuel cells was investigated both numerically and experimentally. Firstly, a three dimensional (3D) PEM fuel cell model was developed, and simulations were conducted using commercial computational fluid dynamics (CFD) ANSYS FLUENT to examine the effect of each bipolar plate materials on cell performance.

Spousal Socio-demographic Gaps and Women's Justification of Wife-beating in Nigeria.

Incidents of violence among intimate partners remains an increasing concern in Nigeria. More disturbing is the fact that some women still justify acts of violence (particularly, wife-beating) from their partners. The purpose of this study is to investigate the impact of spousal demographic gap and other specific demographic constructs in explaining women's justification of wife-beating.
