Parameter Estimation of Proton Exchange Membrane Fuel Cell System Using Sliding Mode Observer
Parameter estimation for health monitoring and sensorless scenario is achieved online via model-based robust state observer. The proposed dynamic algorithm observes a state (output voltage) of fuel cell system (FCS) in the presence of uncertainties and disturbances. Using this observation, membrane conductivity is estimated. The conductivity is function of water content and temperature which gi...
متن کاملExtremum Seeking Control for Power Output Maximization of Proton Exchange Membrane Fuel Cell using Sliding Mode
Due to the nonlinear P-I characteristic of fuel cells, it is very important to implement a maximum power point tracking (MPPT) controller for practical applications. Based on analyzing the output characteristics of fuel cell power system, this paper presents extremum seeking sliding mode control method for MPPT of fuel cell power system under variable temperature and water content conditions. T...

متن کاملDynamic investigation of hydrocarbon proton exchange membrane Fuel Cell
Sulfonated polyether ether ketone (SPEEK) is categorized in a nonfluorinated aromatic hydrocarbon proton exchange membrane (PEM) group and considered as a suitable substitute for common per-fluorinated membranes, such as Nafion, due to wider operating temperature, less feed gas crossover, and lower cost. Since modeling results in a better understanding of a phenomenon, in this study a dynamic o...
متن کاملAn analytic model of membrane humidifier for proton exchange membrane fuel cell
An essential requirement for an operating PEM fuel cell is providing proper water content in the membrane. To avoid water flooding an appropriate water balance is required. Here, an analytic model of a planar membrane humidifier for PEM fuel cell is proposed where the effect of dimensional parameters includes membrane thickness, membrane area and channel hydraulic diameter are investigated. A N...
