High electric conversion efficiency

The main advantages of FC generators are high electrical-conversion efficiency, modularity and very low environmental impact. [Pg.209]

Thermophotovoltaic systems convert the radiant energy produced by fuel combustion directly into electricity. Snch systems can potentially attain high overall conversion efficiencies. Because they may use renewable as well as fossil fnels, they permit a smooth pathway for an environmentally benign method of electrical energy generation (Catalano, 1996). [Pg.260]

The high energy conversion efficiency of solid oxide fuel cells (SOFC), together with their high fuel flexibility, make them an ideal candidate for a better exploitation of fossil fuels, and for an efficient conversion of renewable energy sources into electricity. [Pg.405]

Liu prepared a sandwich type coordination compound (103) from porphyrin and phthalocyanine with the assistance of a microwave. The resulted compounds showed good solubility in conventional organic solvents. The photoelectric conversion properties have been tested with a Gratzel type cell. The results revealed that the sandwich type compound showed better photo-electric conversion efficiency than the corresponding monomeric porphyrin or phthalocyanine precursors. The short-circuit photocurrent of the solar cell with this sandwich type compound as sensitizer, was, as high as 691.31 A cm-2, which was much better, than those of porphyrin or phthalocyanine monomers [100]. [Pg.264]

The combination of high intrinsic interfacial activity at the Pt/ionomer interface and effective catalyst dispersion also provides a key for high energy-conversion efficiency. The overall efficiency of a fuel cell converting fuel to electric power at some voltage, V/gU, across the load, is calculated as ... [Pg.556]

Examples of chronological improvements in high solar to electrical conversion efficiency PEC s are summarized in... [Pg.311]

Parkinson, Heller, and Miller [58] and Lewis and coworkers [59] have shown that metal ion (Ru +, Os +) treatment of the -GaAs surface leads to high solar to electrical conversion efficiencies in these cells... [Pg.384]
