The DMFC fuel cell, with its compact size, simple operability, efficient power output capacity, extremely low operating noise and friendly environmental protection ability, can play an important role whether in the cases where there is a need for uninterrupted power supply such as in cars, trucks, yachts, recreational vehicles, and wild camping, or in the cases where there is a demand for off-grid electrical energy in mobile signal towers, outdoor remote monitoring systems, and extreme outdoor environments.
