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

ABSTRACT
The aim of this paper is to describe the implementation of a lowpower,low-cost 16-bit RISC microcontroller that will act as thecore of a stand-alone security system. The controller is designedto provide moderate-high security at very low cost and to be ableto operate independent of a database. It is designed using 1.5-mSCMOS process from MOSIS and operates at a frequency of 12.5MHz.

Proton Exchange Membrane FuelCell Characterizationf or Electric
Vehicle Applications

ABSTRACT

This paper presents experimental data and an analysis of a proton exchange membrane fuel cell system for electric vehicle applications. The dependence of the fuel cell system’s performance on air stoichiometry, operating temperature, and reactant gas pressure was assessed in terms of the fuel cell’s polarity and power density-efficiency graphs. All the experimen~ were perfor..............etc

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
