“…The typical range for the intercept (V o ) is 0.5-1 V and for the slope (k IV ) ranges from 0.1 to 0.45 V cm 2 /A. [17][18][19] As can be seen in Figure 12A, the optimal TAC decreases with an increase in the intercept (V o ). An increase in the intercept (V o ) brings about a higher system efficiency.…”

Tradeoff between capital cost and the operating cost can be seen in the design of proton exchange membrane fuel cell systems. The polarization curve indicates that operating in the region of lower current densities implies less operating cost (hydrogen fuel) and higher capital cost (larger membrane electrode assembly area). The opposite effects are observed when one operates in the region of higher current densities. Therefore, an appropriate design should take both factors into account and the optimality depends on the corresponding costs of hydrogen and membrane area. An analytical cost model is constructed to describe such an economic balance in a proton exchange membrane fuel cell system. The objective function of the optimization is the total annual cost. Six scenarios are used to illustrate the optimal design based on the total annual cost as cost and materials factors fluctuate.

“…Key requirements for an optimal electrocatalyst, particularly for those based on bimetallic formulations, are a high dispersion and an adequate particle size. The preparation of Pt, Pt-Ru and Pt-Pd-based electrocatalysts from microemulsions has been reported by Escudero et al [39]. The activity of the materials was tested in a H 2 /O 2 or H 2 /air fuel cell using the prepared electrocatalysts as the anode of the fuel cell and a commercial electrocatalyst as cathode.…”

“…[1,16,[31][32][33][34] It is believed that the synthesis of the particles at low temperatures as well as their narrow size distribution leads to better catalytic activity. [31,35] However, the synthesis of Pt-metal intermetallic particles via the microemulsion route was reported only for metals with similar reduction potential, such as Pt:Ag, [36] Pt:Au [37] and Pt:Pd, [38] [39] while the synthesis using metals with largely different reduction potentials has not yet been achieved.…”
