Regenerative energy control system for plug-in Hydrogen Fuel cell scooter
International Journal of Energy Research, 2008Co-Authors: Wai Kean Yap, Vasu KarriAbstract:An intelligent control system was developed using simple control methodologies for an H2-powered Fuel cell scooter with the aid of a built-in microprocessor. This system increases the power input to drive a Hydrogen Fuel cell scooter, particularly during uphill conditions by running both the batteries and the Fuel cell source in parallel. This system also improves the energy management of the scooter by recharging the battery using the Fuel cell as well as automatic switching to the battery source when the Hydrogen Fuel cell is running low on Hydrogen. This system was tested on a bench set simulating a 254 W Hydrogen Fuel cell stack equipped on a 200 W scooter. The test rig set-up depicts a practical scooter running on various load conditions. These results reflect the efficiencies of actual running conditions. The entire operation was embedded in a PICAXE-18 microcontroller for automatic switching between the batteries and the Fuel cell source. An increase in the DC motor efficiency by 6 % has been shown. The uphill angle of the scooter has been increased by 19.3 %, which means the scooter would be able to travel on steeper hills. Copyright © 2007 John Wiley & Sons, Ltd.

Hydrogen Fuel and transport system: A sustainable and environmental future
International Journal of Hydrogen Energy, 2016Co-Authors: Adeel Ahmed, Angelina F. Ambrose, Abul Quasem Al-amin, Rahman SaidurAbstract:This article critically evaluates the introduction of Hydrogen Fuel into the Malaysian transportation system for a sustainable and environmental future. The Malaysian government climate road map and the emission reduction agenda are considered using a framework of environmental sustainability. The framework takes account of national macroeconomic issues considering several feasible options for a sustainable environmental future. Towards that end, there are certain critical developments, particularly as the Hydrogen Fuel option is considered one of the best possible alternatives compared with several other renewable energy choices for sustainable growth. While the benefits of prioritizing a modern emission-free future transport system are great, often issues raised regarding how a national economy can deliberate and implement such policy options become contentious. Therefore, this study will help national policymakers take into account sustainability and environmental considerations within the framework of introducing an effective Hydrogen Fuel economy into the modern transport system.

A Dynamic Simulation Tool for the Battery-Hybrid Hydrogen Fuel Cell Vehicle
Fuel Cells, 2006Co-Authors: R M Moore, J M Cunningham, S. Ramaswamy, Karl-heinz HauerAbstract:This paper describes a dynamic Fuel cell vehicle simulation tool for the battery-hybrid direct-Hydrogen Fuel cell vehicle. The emphasis is on simulation of the hybridized Hydrogen Fuel cell system within an existing Fuel cell vehicle simulation tool. The discussion is focused on the simulation of the sub-systems that are unique to the hybridized direct-Hydrogen vehicle, and builds on a previous paper that described a simulation tool for the load-following direct-Hydrogen vehicle. The configuration of the general Fuel cell vehicle simulation tool has been previously presented in detail, and is only briefly reviewed in the introduction to this paper. Strictly speaking, the results provided in this paper only serve as an example that is valid for the specific Fuel cell vehicle design configuration analyzed. Different design choices may lead to different results, depending strongly on the parameters used and choices taken during the detailed design process required for this highly non-linear and n-dimensional system. The primary purpose of this paper is not to provide a dynamic simulation tool that is the “final word” for the “optimal” hybrid Fuel cell vehicle design. The primary purpose is to provide an explanation of a simulation method for analyzing the energetic aspects of a hybrid Fuel cell vehicle.
