Analysis of individual PEM fuel cell operating parameters for design of optimal measurement and control instrumentation

Number of applications, power span and implementation areas for PEM (proton exchange membrane) fuel cells are increasing daily. All these applications require adequate measurement and control that will ensure optimal functionality of PEM fuel cell. Number of measuring quantities, especially in high – power systems, is numerous so pricing of measurement and control equipment is appreciable. In this paper we have implemented simple PEM fuel cell model and analyzed individual influences of fuel cell operating parameters, like temperature, partial pressures and membrane humidity. We have found out that influence of each operating parameter on fuel cell’ s power output is different. Therefore we can design measurement and control equipment with different complexity. With that we can ensure optimal control of fuel cell’ s output power and efficiency without use of costly equipment.
