Two types of recently developed portable fuel cell systems are described: one with dc output and one with ac output. These systems consist of a small fuel cell stack, two hydrogen cylinders, and a power converter. They are completely contained in one cabinet that can be separated into two sections,
## Characterization of composite SOFC cathodes The performance of Pt/YSZ and LSM/YSZ composite SOFC electrodes as a function of the electrode composition is investigated experimentally. The qualitative features of the impedance spectra are similar for both cathodes; in particular, in both the elect
There is growing interest in the replacement of batteries by fuel cells for portable consumer electronics such as cellular phones, laptop computers, digital cameras etc. At first sight, comparisons with batteries based on performance and convenience are encouraging. However, the cost and safety aspe
