Experimental methods and static quantum calculations can't always give the most realistic picture of the reaction dynamics that laser pulse irradiation induces. Semiclassical dynamics simulations offer an alternative. Molecular response to ultrashort laser pulses

Date May 22, 1998A electrochemical power generation system comprising a plurality of fuel cells electrically connected to each other, each fuel cell having an anode and a cathode. A plurality of first passage means are associated with and defined by the anodes and a plurality of second passages means are associated with and defined by the cathodes. The first passage means is divided into a first group and a second group of passage means. A third passage means is connected to the inlets of the first group to supply fuel gas to the first group. A fourth passage means receives the anode exhaust gas from the first group. The fourth passage means is divided into first and second streams, the first stream is supplied to the third passage means and the second stream is supplied to inlets to the second group of the first passage means as fuel. Solid oxide fuel cells or molten carbonate fuel cells are used.
