Traditionally, a wide variety of methods are available for hydrogen production from conventional sources such as natural gas, coal, oil and etc. Their application, however, contributes to emission of ozone depleting gases such as CO2. This paper reviews the recent developments of hydrogen production methods related to solar-hydrogen production for remote area application. The methods discussed are thermochemical, photoelectrochemical and electrochemical where water is the basic raw materials. From this review, the low overall efficiency of photoelectrochemical and thermochemical process makes them non-attractive for remote areas application. This paper concludes that the most suitable method for hydrogen production for remote area application is electrochemical process where electrolyzer represents the most important process to obtain hydrogen without any emission of air pollutants or greenhouse gases. This paper will be useful for solar hydrogen system manufacturers, academicians and researchers.

This aircraft is equipped with split drag flaps in order to perform directional motion. One of the split drag flaps will be deflected to generate yawing moment. This yawing moment is generated through the drag that is produced upon deflection of flaps. The study was carried out using Computational Fluid Dynamics (CFD) for various sideslip angles (β) and various flaps deflection angle (δT). The simulation was conducted at 0.1 Mach number (35 m/s) and results in terms of coefficient such yawing and rolling moment are tabulated in order to determine the stability of the aircraft. The result reveals that the aircraft is directionally unstable. This is as expected because the aircraft does not have any vertical tail configuration to provide the yawing moment. However, high deflection of split flaps can still generate adequate restoring moment for the aircraft.

The numerical model using set of equations are valid for a single cell fuel cell with flow field channel and membrane electrode assembly (MEA). The numerical model was validated against published data with good agreement. Subsequently, two new flow field designs with different active area and cross sectional dimensions was introduced and analyzed using the model developed. The simulations revealed that bipolar plates with larger active area drawn higher power density as predicted.
