Abstract

Gasolines sold at our service stations typically have an octane rating between about 87 & 93, & fuels of such octane values are satisfactory for most automotive engines. However for high performance engines in particular, fuels of even higher octane ratings are required. Octane is a measure of a gasoline s antiknock performance its ability to resist knocking, which is a metallic rattling or pinging sound that results from uncontrolled combustion in the engine s cylinders. It may preven ....etc

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 performed by loading the fuel cell with resistive heater ....etc
