“…Although microalgae have great application prospects in the production of bioenergy and aquaculture wastewater treatment, the recovery of microalgae is difficult due to small cells, low cell concentration, small specific gravity, and easy suspension in water, which can seriously lead to microalgae. Serious flooding, causing secondary pollution of water resources [15][16]. Several immobilization methods are compared below.…”

Microalgae are potential renewable biodiesel raw materials, with the advantages of high oil yield per unit, no competition with farmland, and synergistic carbon dioxide fixation. However, microalgal biodiesel has not been widely commercialized so far, and the high cost of cultivation and recovery makes its product price less competitive with traditional petrochemical diesel. The main purpose of this paper is to study the design of experimental teaching of environmental microbiology based on the content of microalgae cultivation in the context of big data. Based on the analysis of the current situation of biology experiment teaching, this paper decides to adopt the method of design experiment teaching to carry out biology experiment teaching in high school. Experiments show that the impact of teaching on students' biological learning accounts for 31%, ranking after personal interests, which not only shows that teaching has a very important position in the factors that affect students' biological learning, but also shows that teaching is interesting, scientific, and diverse. Sex needs to be improved to further promote students' interest in biology.

“…In this paper, the influence on the distribution of contact pressure of the uncertainties of the mechanical design parameters is study numerically. Deterministic model developed in [16] is used to simulate of the behavior of the fuel cell, in particular the contact pressure, from determined and constant parameters. The effect of the uncertainties parameters on the performance of the cell and in particular the distribution of the contact pressure between each fuel cell components is analyzed.…”

“…Two-dimensional geometry with the plane strain assumption was adopted for the model described in the present paper. Because the dimension of BBP channel in its longitudinal direction was much larger than channel width and GDL thickness, plane strain assumption was reasonable [27,52,53]. With this hypothesis, the normal and shear strains in y direction were zero, namely ε y = γ xy = γ yz = 0.…”

The deformation of gas diffusion layer (GDL) under compacting pressure has a close relationship with transport properties, and electrical and thermal conductivity of proton exchange membrane fuel cell (PEMFC). In this paper, two kinds of GDL material models with different material parameters are studied with the finite element method (FEM). Taguchi orthogonal experiments and analysis of variance (ANOVA) are performed to determine their effects on mechanical analysis of GDL deformation in PEMFC. Finally, the effects of material parameters on GDL diffusion and electrical performance are discussed. The results reveal that elastic modulus (E) is the only factor affecting the maximum displacement for GDL with isotropic model when the Poisson's ratio (ν) is in the range of 0–0.1. For orthotropic model, the through‐plane elastic modulus (Ez) has a great impact on both the deformation and contact pressure. In‐plane elastic modulus (Ex) and through‐plane shear modulus (Gxz) have significant influences on contact pressure. Ez has a great impact on diffusion and electrical performance of GDL, while the effects of Ex, Gxz and ν are negligible. In addition, orthotropic GDL material model and the parameters utilized are effective in analyzing the deformation of GDL.
