Abstract
A fuel cell system comprises at least one fuel source (e.g., methanol or methanol solution) In a storage tank, tubes and/or flow channels that provide the fuel to the fuel cells via tubes and/or flow channels, which are used to connect the different fuel cells and/or supply the fuel to all or some of the fuel cells, one or more ultrasonic transducers, which are set inside or are associated with the tubes and/or flow channels through which the fuel (e.g., methanol or methanol solution) is supplied to the fuel cells. The transducers can optionally be integrated with the tubes and/or flow channels of the fuel cell systems. The ultrasonic transducers are able to generate high frequency vibration, and the fuel is able to transmit the high-frequency vibration through the liquid fuel body, to increase the performance of the fuel fed fuel cell system.
