fuel cost
2.Since fuel cost make a large proportion in transportation costs, topping above 50 percent with a higher fuel price. Complete management and good use of fuel, especially the effective control of fuel cost makes a great effect on transportation economy, and hence is an effective way to reduce transportation costs.
6.In a direct-hydrocarbon solid oxide fuel cell (D-H SOFC) , hydrocarbon (or alcohol) fuels are fed directly to anode with little or no humidity. The problems related to the traditional hydrogen fuel such as cost, storage, and security can be eliminated in such solid oxide fuel cells (SOFCs) and D-H SOFC has been a new hotspot in SOFC research area.
