Abstract
The invention relates to a system and method of operating alkaline exchange membrane fuel cells in a bipolar configuration. The system () may include a first fuel cell (A) and a second fuel cell (B) adjacent to the first fuel cell. Each of the first and second fuel cells may include: a cathode configured to generate hydroxide ions from water, oxygen and electrons, an anode configured to generate water and electrons from the hydroxide ions and hydrogen received from a hydrogen source, and an alkaline exchange membrane configured to transfer the hydroxide ions from the cathode to the anode, and to transfer water from a vicinity of the anode to a vicinity of the cathode. The first fuel cell (A) and a second fuel cell (B) are connected by a porous bipolar plate (A) positioned inbetween. A pressure profile across the first bi-polar plate may drop from higher level near the anode of the first fuel cell (A) to lower level near the cathode of the second fuel cell (B) so that water may be transferred from the anode of the first fuel cell (A) to the cathode of the second fuel cell (B).
