✦ Synopsis

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, making it easy to move. Each system can generate power within 5 min of the start-up time and can supply between 200 and 250 W of power for more than 6 h using two 6.7-liter hydrogen cylinders. The dc-output system supplies dc 55 V for telecommunications use and dc 12 V for general use, and the ac-output system supplies ac 100 V. The output power of these systems can be increased by operating multiple units in parallel. These systems generate power quietly and cleanly, and are thus suitable for use as an indoor emergency-power source for telecommunications use and for various types of equipment.
