  • Patent number: 11302932
    Abstract: A bipolar plate having side ports is described for use with an electrochemical cell. A side port having a high aspect ratio will have an effect on the partial pressure of the reactant gasses and prevent high pressure drop of the working fluid transport to the electrodes. The membrane electrode assembly may have a high aspect ratio and the port opening may be on the long side of the bipolar plate. The electrochemical cell may be configured in an enclosure that is maintained at less than atmospheric pressure which further increases the need for low pressure drop fuel deliver to the electrodes, especially in electrochemical compressor applications.
