Water management and stack design for solid polymer fuel cells

摘要: Abstract Water management has a major impact in the solid polymer fuel cell on overall system power, cost and efficiency. Single stack performance may be adversely affected by formation of liquid water, dilution reactant gases water vapour, or dehydration membrane. Peak power is achieved typically at current densities which limited mass transport. Improved higher not only increases peak efficiency but changes profile curve resulting improved stability near operating point. Fuel can accomplished number approaches include design, conditions, hardware membrane electrode assembly design. A these techniques have been successfully applied to both single cells stacks. However, options available for assessed from an engineered point view.
