Fractional factorial design of experiments for PEM fuel cell performances improvement

Solid oxide fuel cell stack temperature estimation with data-based modeling – Designed experiments and parameter identification

“…Only the k first elementsà 0…k are required for the k-step-ahead prediction and these are found recursively by using the condition (12).…”

“…A k-step-ahead prediction for T max and T min is calculated by using the model, (1), and the predictor obtained with (10)e (12) . Fig.…”

RuxCrySez electrocatalyst loading and stability effects on the electrochemical performance in a PEMFC

“…In order to expand the size of tested MEAs, the preparation methodology should also be improved. An optimal operation condition study is in progress using an approach based on fuel cell simulations [20][21][22].…”

Analysis of operating parameters considering flow orientation for the performance of a proton exchange membrane fuel cell using the Taguchi method

“…In recent years, several researchers employed Taguchi method to evaluate the respective impacts of those parameters on the performance of PEM fuel cell and to reduce the number of experiments when they studied many parameters [9][10][11][12][13][14][15]. Grujicic and Chittajallu [9,10] applied a two-dimensional model coupled with a nonlinear constrained optimization algorithm to determine an optimum design of the fuel cell for the operation and the geometrical parameters of cathode such as the air inlet pressure, the cathode thickness, and length and the width of shoulders in the interdigitated air distributor.…”

“…Torchio et al [14] applied it to operation parameter effect investigation on the cogenerative performance of a PEM fuel cell stack, through a statistical methodology used for the experimental data analysis by 2 4 factorial design (four parameters, each at two levels, were anode and cathode flow inlet temperature; cathode flow dew point temperature; cathode flow stoichiometry to run all 2 4 = 16 treatment combinations). Dante et al [15] used a fractional experimental design supported by a statistical methodology to analyze how four parameters (hydrogen and oxygen pressures and flow rates, each at two levels, eight treatment combinations) affected the electric power output of a stack.…”
