BaUard Power Systems, the leader in the manufacture of PEEC stacks, has sold at least fifty 3- to 5-kW units worldwide. BaUard is involved in a program in Canada to demonstrate a 120-kW PEEC stack to power a transit 20-passenger, 9752-kg bus. Eor this demonstration, on-board compressed hydrogen, sufficient for 150-km range, is the fuel. 

Siemens AG has been involved in R D on PFFCs, and Vickers Shipbuilding Engineering Ltd. (United Kingdom) is evaluating PFFCs from Ballard Power Systems for power generation. A 35-ceU stack was successfully tested for more than 300 h. Plans are under way to test a 20-kW PEFC. 

Ballard Power Systems, in conjunction with the province of British Columbia and the government of Canada, have converted a diesel bus for Vancouver, B.C. Transit (43). This 9.1-m vehicle is powered by a 105-kW fuel cell. Gaseous hydrogen, stored on board the bus in DOT-approved glass-wound composite cylinders operating at 20.7 MPa (3000 psi), provides the necessary fuel requited for the 150-km projected vehicle range.

Other organi2ations have assumed important positions in the field of patent documentation. IFl/Plenum Data Corp. (formerly Information for Industry) began in 1955 to index U.S. chemical patents by the Uniterm Index system. Uniterm indexing was eventually extended back to 1950. The acquisition in 1971 of Du Font s in-house indexing system and staff resulted in a more powerful system, the Comprehensive Data Base (CDB), which now covers U.S. chemical patents frommid-1964 to date. 

A photovoltaic (PV) solar power system is a complete electrical source that uses solar cells to directly convert light energy into electricity. The system can be self-contained and completely autonomous or it can work in tandem with other conventional fuel-based sources of power to offer robust power availabihty.

Current Status The U.S. Department of Energy (DOE) and its private-sector collaborators have substantially advanced the development of gasification-based power systems during the last decade. This section describes the current status for the various types of gasifiers used. 

Cost of Gasification-Based Power Systems In the U.S. power industry the capital cost is usually reported in dollars per kilowatt ( /kW) and the cost of electricity (COE) in mills per Idlowatt-hour (a mill is one thousandth of a dollar). Estimation of capital cost and COE... 

While comparison of the absolute capital costs and costs of electricity among different power systems is difficult and uncertain, the structure of these costs is rather typical, and the costs of component units are usually within known ranges. For an oxygen-blown IGCC power system, the breakdown of the capital cost for the four component units is air separation plant (11 to 17 percent), fuel gas plant (33 to 42 percent), combined-cycle unit (32 to 39 percent), and balance of plant (2 to 21 percent). The breakdown of the cost of elec tricity is capital charge (52 to 56 percent), operating and maintenance (14 to 17 percent), and fuel (28 to 32 percent). 

The capital investment required for gasification-based power systems is 1400 to 1600 /kW (1994 US dollars) and is projected to become less than 1200 /kW in the year 2000 because of the higher efficiency associated with gas-turbine combined-cycles currently being designed by turbine vendors.
