Introduction to methanol fuel cells

Methanol fuel cells are divided into direct methanol fuel cells (DMFC) and recombinant methanol fuel cells (RMFC), which are mainly developed for portable devices such as mobile phones and notebook computers. Although the energy density of methanol fuel cells is not as high as other types of fu…
Status and development of grading equipment

Grading is an extremely important preparation task during the beneficiation process. Grading can effectively separate the coarse and fine particles, thus avoiding the excessive pulverization of the fine-grained minerals, reducing unnecessary e…
