Fuel cell technologies have several applications in stationary power production, such as units for primary generation, grid stabilization, systems adopted to generate backup power, and combined-heat-and-power configurations (CHP). The main sectors where fuel cells been employed are (a) micro-CHP, (b) large applications, (c) UPS, IPS. size is strongly related the needed from load. Since this sec...

We have developed a system that uses two 1D interferometric phase projections for reconstruction of 2D water content changes over time in situ in a proton exchange membrane (PEM) fuel cell system. By modifying the filtered backprojection tomographic algorithm, we are able to incorporate a priori information about the object distribution into a fast reconstruction algorithm which is suitable for...

A dynamic fuel-cell model for high-temperature PEM fuel cells with PBI membranes has been developed in Simulink. In such models it is common to use the current density as input variable, but this model uses a different approach. The current density is regarded as an unrealistic control variable, since it cannot be controlled directly. Instead, it is possible to simulate the effect of changing t...
