Hydrogen ideal primary fuel

For fuel cells operating at low (<100°C) and intermediate temperatures (up to 200°C), Fl2 and H2/ C02 (with minimal amounts of CO) are the ideal fuels the F12/C02 gas mixture is produced by steam-reforming/water-gas shift conversion, or partial oxidation/shift conversion of the primary or secondary organic fuels. Flydrogen is a secondary fuel and, like electricity, is an energy carrier. On a large scale, hydrogen is produced from the primary sources—natural gas, coal, or oil. For... 

Flow cells are ideal for stors e systems in remote locations. Vanadium redox systems, for instance, deliver up to 500 kW for up to ten hours. Zinc-bromine systems have been produced for 50-kWh and 500-kWh systems to reinforce weak distribution networks or prevent power fluctuations. Hydrogen fuel cells can potentially do almost anything a battery can do provide backup power, perform power leveling, run handheld devices, and supply primary or auxiliary power to cars, trucks, buses, and boats. In many cases they are more efficient than petrochemical fuels. A hydrogen fuel cell in a vehicle that uses an electric motor, for example, can be 40 to 60 percent efficient, compared with the 35 percent peak efficiency of the internal combustion engine. 

Stationary combined heat and power (CHP) devices are often considered the primary application of high-temperature PBI-based fuel cells. These devices are used to provide both electricity and heat (in the form of hot air or water) to small-scale residential homes or large-scale industrial plants using hydrogen derived from the widely distributed natural gas network. PBI MEAs are ideally situated for combined heat and power devices because they efficiently provide electricity while generating heat as a by-product. Furthermore, these devices could be used to provide reliable backup power to residential homes, hospitals, servers, etc.
