Smart Fuel Cell C20-MP Hybrid Fuel Cell Power Source

摘要

The SFC C20-MP now utilizes fourth-generation conductive membrane technology in order to both increase system power density and mitigate the effects of methanol crossover across the DMFC membranes. Upon delivery of the upgraded units, CERDEC performed a series of test regimes to determine the operational capabilities of the C20-MP including fuel efficiency and power energy density. These tests confirmed that the C20-MP units are capable of achieving net system efficiencies as high as 21% based on the LHV of methanol. Testing also showed that the SFC systems were capable of providing upwards of 20 Watts of net continuous power at a power density of 10.25 Watts/kg. The calculated system energy density is 420W hrs/kg for a 72 hour, 20 Watt mission. The rest of this paper will discuss the results and findings in greater detail.
