Document Summary
Direct methanol polymer electrolyte fuel cell: subset of pem, applications, miniature, consumer electronics, battlefield, features, modified pem components, methanol crossover lowers efficiency. Cells and stacks: single cells are arranged into stacks to increase total voltage and power output, cathode: 1. 2v, anode: 0. 0 v, total cell: 1. 2 v per cell. Alkaline fuel cell: applications, space, transportation, features, high performance, very sensitive to co2, expensive pt electrodes. Phosphoric acid fuel cell: applications, distributed power plant, combined heat and power, some busses, features, some fuel flexibility, high efficiency in cogeneration 85, established service record, platinum catalyst. Molten carbonate fuel cell: applications, distributed power plant, combined heat and power, features, fuel flexibility (internal reforming, high efficiency, high temperature, good for cogeneration, base material, nickel electrodes. Steam reformation of natural gas: mix steam with natural gas, breaks natural gas into hydrogen and carbon dioxide, 95% of hydrogen comes from this.
