FRONTIERS OF TECHNOLOGY STUDY - ADDITIONAL DATA FOR PRELIMINARY IMPLEMENTATION REPORT, SECTION IV: FUEL CELLS IN URBAN TRANSPORTATION

THE REPORT DESCRIBES FUEL CELLS AS URBAN TRANSPORTATION VEHICLE PROPELLANTS. ECONOMIC FEASIBILITY CRITERIA ARE APPLIED TO VARIOUS FUEL CELL TYPES; THE LEAST COSTLY DESIGNS ARE, HOWEVER, NOT YET MARKETABLE. SEVERAL SPECIFIC FUEL CELLS ARE ANALYZED ACCORDING TO THEIR PERFORMANCE, INCLUDING HYDROGEN, HYDRAZINE, AMMONIA, METHANOL, AND HYDROCARBON CELLS. IN EACH CASE POTENTIAL PROBLEM AREAS ARE DISCUSSED. AMONG THE DRAWBACKS MOST EVIDENT IN CURRENT STATE-OF-THE-ART ARE: (1) LIMITED OVERLOAD CAPABILITY WHICH NECESSITATES RELATIVELY BULKY AND EXPENSIVE UNITS; (2) UNACCEPTABLY EXPENSIVE COMPONENTS; AND (3) AN UNDESIRABLE UNIT SIZE POWER-OUTPUT RATIO. OF MAJOR CONCERN IN THE REPORT ARE PROJECTIONS FOR FUTURE DEVELOPMENT. SPECIFICALLY THE AUTHORS NOTE THAT THE MOST EASILY EMPLOYED AND EFFICIENT FUELS ARE THE MOST COSTLY, WHILE INEXPENSIVE HYDROCARBON FUEL CELLS STILL REQUIRE SUBSTANTIAL RESEARCH AND DEMONSTRATION. THREE BREAKTHROUGHS REQUIRED FOR EVENTUAL USE OF FUEL CELLS AS TRANSIT VEHICLE PROPELLANTS ARE: (1) INEXPENSIVE ELECTROCATALYSTS TO REPLACE THE PLATINUM CURRENTLY USED; (2) IMPROVED ELECTRODE STRUCTURES TO IMPROVE OUTPUT; AND (3) IMPROVED OVERALL SYSTEM ENGINEERING. /UMTA/
