The efficiency of fuel cell is higher than the Carnot engine. To date, cost is the daunting factor for making the proton exchange membrane fuel cells (PEMFC) commercially viable in appliances. Over the years, a significant research activity has been witnessed in cutting down the cost that is involved in making the individual components of a fuel cell. However, relatively fewer efforts have been put into minimization of the cost of integrating a PEM fuel cell (PEMFC) system. This work is focused on the reduction in cost of PEMFC stack system (st ....etc

Design and Development of a Dual Fuel Diesel-LPG Controller
Abstract
Towards the effort of reducing pollutant emissions from direct injection (DI) Diesel engines. The use of Liquefied Petroleum Gas (LPG) as an alternative fuel is a promising solution. After scrutinizing the results, a Dual fuel Diesel-LPG Controller was developed for optimizing the performance on different loads (20% to 120%) without making any modifications in the engine design.
Key Words: Duel Fuel Genset, Diesel-LPG Controller, LPG.

High Frequency Low Cost DC-AC Inverter Design with Fuel Cell
Source for Home Applications
ABSTRACT:
This paper presents a new design of highfrequency Dc/Ac inverter for home applications using fuel cellsor photovoltaic array sources. A battery bank parallel to the DClink is provided to take care of the slow dynamic response of thesource. The design is based on a push-pull dc/dc converterfollowed by a full-bridge PWM inverter topology. The nominalpower rating is 10kW. Actual design parameters, procedure andexperimental results of a 1 ....etc

Fuel cells are a proven power source for manned spacecraft where they generate electrical power from stored hydrogen and oxygen that are carried in cryogenic liquid form. The world?s petroleum production is about to pass its peak, so a world wide development effort is being directed into adapting these high efficiency fuel cells into powering automobiles, buses and trucks. Fuel cells are more efficient than the secondary batteries used. First Alkali fuel cells are used in aircrafts, but now a days fuel cells using Proton Exchange Membrane are ....etc

Abstract
In the urban traffic mode, the engine is known to beoperated mostly in a transient state. However, the wide operatingrange, the inherent nonlinearities of the induction process andthe large modeling uncertainties make the design of the fuelinjectioncontroller very difficult. Even though a sliding modefuel-injection control method is in good agreement with thecharacteristics of the system, the unavoidable large time-delaybetween control action and measurement causes the p ....etc
