Air Cells Using Negative Metal Electrodes ...

Research on the produce of renewable energy as a source of solar power has continuously advanced. We have proposed an energy cycle that uses solar-pumped pulse lasers and base metal nanoparticles. Here, Fe and Al nanoparticles were prepared by laser ablation in liquid for the energy cycle. Solar power was confined in base metal nanoparticles. Metal plates were fabricated by sintering metal paste with base metal nanoparticles. Electricity was generated by air cells using the sintered metal plate. A highly repetitive laser pulse, which was an alternative to lasers driven by solar power, was used for laser ablation in liquid, and metal oxides (Fe3O4 or Al2O3) were reduced and metal nanoparticles were fabricated. Metal plates with a low electrical resistance were fabricated by sintering them at a low temperature of 520 K. The electrical properties of the air cells fabricated using sintered paste with nanoparticles as negative electrical cathodes were the same as those of the air cells fabricated in a blast furnace. It was found that the sintered metal nanopaste could be used for air cells.
