For this application, fuel cell-based power sources delivering a permanent electrical power of 20–50 W and which can be carried permanently by a soldier are required. A further prerequisite is that these cells are self-contained, meaning that they can be operated without an external power suppl...
#15: American Elements Develops Low Cost Fuel Cell Material for U.S. Department of Energy Program The Challenge Solid oxide fuel cells (SOFCs) offer the world a potential game changing means to produce energy from hydrocarbons; far cleaner and more efficient than combustion engines. However, man...
Water uptake capacity (WUC), swelling property, area change, dynamic mechanical analysis, ion exchange capacity (IEC), AC impedance analysis, hydrolytic stability, and oxidative stability analyses were performed for fuel cell applications. Although FBA does not have a crystal structure, the synergy ...
PROBLEM TO BE SOLVED: To provide a property evaluation method of a fuel battery capable of separating a component caused by ion transport number reduction according to a simple method from reduction from a theoretical open circuit voltage in an open circuit voltage of a fuel battery cell.OKADA ...

Carbon represents the main nutrient element forming algal cell skeletons (about 50%), and carbon nutrition realizes the most expensive figure of algae nutrition. The use of an organic carbon source suggests a dual objective: the first as a cheap carbon source, while the second reduces the extern...
2. Fuel Cell (FC) Model The FC operates similarly to a battery with an anode and a cathode, producing a DC voltage. The output voltage of the FC exhibits a noticeable degree of regulation with increasing current, as shown in Figure 1a, where the voltage–current characteristics of a single...
