“…First, the 3D surface model is characterized from the images and is subsequently imported into computer-aided design (CAD) software (e.g., SolidWorks) to generate a 3D volume model after necessary error corrections. In fact, similar methods are widely used in metal foam reconstruction for thermal analysis, mechanical behavior analysis, and so on.…”

Porous flow fields distribute fuel and oxygen for the electrochemical reactions of proton exchange membrane (PEM) fuel cells through their pore network instead of conventional flow channels. This type of flow fields has showed great promises in enhancing reactant supply, heat removal, and electrical conduction, reducing the concentration performance loss and improving operational stability for fuel cells. This review presents the research and development progress of porous flow fields with insights for next-generation PEM fuel cells of high power density (e.g., ∼9.0 kW L–1). Materials, fabrication methods, fundamentals, and fuel cell performance associated with porous flow fields are discussed in depth. Major challenges are described and explained, along with several future directions, including separated gas/liquid flow configurations, integrated porous structure, full morphology modeling, data-driven methods, and artificial intelligence-assisted design/optimization.

A variational formulation of a beam model is presented for predicting the inelastic and geometrically nonlinear mechanical behavior of cellular and truss‐based architected materials. Emphasis is placed on the constitutive description of base materials commonly used in additive manufacturing, including polymers and metals, and the derivation of effective incremental potentials incorporating the effects of damage and viscoplasticity. The model is demonstrated in a variety of problems including the fracture of polymeric honeycombs, the tightening of woven architected materials, as well as the compression of metallic foams. The model's easy calibration–on the basis of single‐strut tests–and its successful validation—through experiments of additively manufactured specimens–indicate its promise as an efficient design tool for architected materials within a wide range of engineering applications.
