“…Taguchi method is known as a robust tool for the experimental optimization of a model. This method is used to estimate the significance of each parameter and to deduce the optimal combination of different design factors 20 . The analysis of the experimental data obtained from Taguchi design runs is carried out on MINITAB software using the model as given by Equation ():

Additive manufacturing by fused filament fabrication provides an innovative manufacturing process for new design vision and complex geometry components. This study aims to establish the relationships between the process parameters and the mechanical properties of 3D printed parts using Taguchi design of experiment. The proposed method also enables the study of the filling orientation effects on the cohesion of the printed layers and the overall fracture behavior. We reviewed and optimized the effects of the critical parameters of process such as the layer thickness, the temperature, the print speed, and the filling orientation on Young's modulus and tensile strength. Then the effect of raster angle on the cohesion between the printed layers, as well as the failure modes were analyzed. The results show that the layer thickness and the filling angle are more influential on the mechanical properties. An analysis of the fracture surfaces of tensile specimens was also performed and it indicated a fracture following the filling direction. Furthermore, the fill angle 0/90° shows the best adhesion between the printed layers.

“…The unnumbered arrows show the direction of air flow to achieve a superior performance (such as system-level specific energy 500-800 Wh kg −1 for the operating time of 4 h, vide infra), peripheral systems (such as humidifiers and heaters used in automotive PEMFCs) must be avoided. For this reason, PEMFC systems with a dead-end (occasionally purged to remove water and crossover N 2 ) [9] anode and an open cathode are commonly used in UAV applications [4,5,[10][11][12][13][14][15][16][17]]. An exemplary scheme of such system is shown in Figure 1, wherein dry H 2 is supplied from a high-pressure tank (1) through pressure reducer (2), pressure sensor (3), and fast electromagnetic valve (4) into the anodic compartment (5) of the stack.…”

Open-cathode PEMFCs for unmanned aerial vehicles operate at a near-ambient temperature, which requires high super-stoichiometric air flow rates to remove heat. This, in turn, makes the stack vulnerable to drying out. Using a combination of experimental measurements with a 1.2 kW stack and 3D multiphysics modelling, we show that the design of the corrugated metal bipolar plate with a height above the commonly used 1.05 mm and with cathode cooling channels wider than air-suppling channels allows for a more efficient heat removal at lower air flow rates, thus assuring a wider range of operating parameters, while maintaining adequate hydration. The self-humidifying stack attains 1000 W kg −1 power, and the full system with a nominal runtime of 4 h attains specific energy of 700 Wh kg −1 .

“…Zervas et al [15] performed a phosphoric acid fuel cell (PAFC) system optimization study based on meta-models that were derived by applying the linear regression and the RBF neural network methodology on the results produced by a CFD model. The optimization of different operating and design parameters on PEMFC using the Taguchi method was performed by Karthikeyan et al [16], Solehati et al [17], and Sasmito et al [18]. Grujicic and Chittajallu [19] utilized a single-phase two-dimensional electrochemical model, coupled with a nonlinear constrained optimization algorithm, which was solved using sequential quadratic programming (SQP) to obtain the operational and geometric parameters for achieving the maximum electric current in a PEMFC.…”

The membrane electrode assembly (MEA) plays an important role in the proton exchange membrane fuel cell (PEMFC) performance. Typically, the structure comprises of a polymer electrolyte membrane sandwiched by agglomerate catalyst layers at the anode and cathode. Optimization of various parameters in the design of MEA is, thus, essential for reducing cost and material usage, while improving cell performance. In this paper, optimization of MEA is performed using a validated two-phase PEMFC numerical model. Key MEA parameters affecting the performance of a single PEMFC are determined from sensitivity analysis and are optimized using the response surface method (RSM). The optimization is carried out at two different operating voltages. The results show that membrane thickness and membrane protonic conductivity coefficient are the most significant parameters influencing cell performance. Notably, at higher voltage (0.8 V per cell), the current density can be improved by up to 40% while, at a lower voltage (0.6 V per cell), the current density may be doubled. The results presented can be of importance for fuel cell engineers to improve the stack performance and expedite the commercialization.
