This review summarizes recent advances in the application of 3D printing (additive manufacturing) for the fabrication of various components of hydrogen fuel cells with a polymer electrolyte membrane (HFC-PEMs). This type of fuel cell is an example of green renewable energy, but its active implementation into the real industry is fraught with a number of problems, including rapid degradation and low efficiency. The application of 3D printing is promising for improvement in HFC-PEM performance due to the possibility of creating complex geometric shapes, the exact location of components on the substrate, as well as the low-cost and simplicity of the process.

- This text discusses the production of polymer composites using recycled PET-based matrices, emphasizing the potential to create materials with properties similar to virgin polymers through glycolysis.
- A kinetic model for the glycolysis process explains how different compounds and temperatures interact during the breakdown of PET, assessing the roles of ethylene glycol and other glycolysis agents.
- Experimental methods, including FTIR spectroscopy and gel permeation chromatography, were utilized to verify the model and analyze the resulting molecular weight distributions and compositions of the glycolysis products.
