International Journal of Hydrogen Energy, 1994
Abstract Present fuel cell designs require more development before they can make a large impact on future energy conversion markets. Today, they must use common fuels such as natural gas, but they in fact operate on hydrogen. They must therefore be integrated with chemical plants which may be regarded as dispersed refineries.

Abstract : Processes to remove jet fuel components harmful to fuel cell performance were tested in simulated and actual cyclic operation using improved molecular sieves. Improved aromatic absorption performance on the lithium X sieve was achieved by pretreating the sieve with high water loading at elevated temperatures.

FUEL CELLS – MOLTEN CARBONATE FUEL CELLS | Cells and Stacks
2009The molten carbonate fuel cell (MCFC) operates at temperatures around 650 °C, and uses an electrolyte of molten alkali metal carbonates. The electrolyte places severe constraints on the way that stacks are engineered, because it is corrosive and can migrate from the cells through the liquid or vapor phase causing degradation of the catalysts used for ...

Biochemical Society Transactions, 1983
Microbial fuel cells containingProteus vulgaris and oxidation-reduction (“redox”) mediators were investigated. The bacteria were chemically immobilized onto the surface of graphite felt electrodes, which supported production of continuous electric current and could be reused after storage A computer-controlled carbohydrate feed system enabled the cell ...

Fuel cells are electrochemical devices capable of converting the chemical energy of a fuel (usually hydrogen, but also hydrocarbons and alcohols) into electricity and heat. Positive characteristics like high efficiency, low pollutant emissions and few maintenance requirements motivated a strong interest in this technology during the last decades, with ...

Publisher Summary Mechanical heat engines generally use the heat released by the reaction of a chemical substance (fuel) with oxygen (usually from air). The heat is then upgraded to mechanical energy by means of rather complicated machinery. It is the outcome of the millenarian struggle to control and use fire. Converting chemical energy directly into

FUEL CELLS – MOLTEN CARBONATE FUEL CELLS | Overview
2009The molten carbonate fuel cell (MCFC) emerged during the twentieth century as one of the key fuel cell types. It uses an electrolyte of alkali metal carbonates, operates typically at 650 °C, and is best suited to hydrocarbon fuels such as natural gas, coal gas, or biogas.

FUEL CELLS – MOLTEN CARBONATE FUEL CELLS | Cathodes
2009The molten carbonate fuel cell (MCFC) operates at temperatures around 650 °C and uses an electrolyte of molten alkali metal carbonates. Oxygen and carbon dioxide are fed to the cathode and fuel to the anode of the fuel cell. The key electrochemical reaction at the cathode is the reduction of oxygen and reaction with carbon dioxide to form carbonate ...
