Design of galvanic cells using simple, low-cost paper

Abstract

This article's stated goal is to give teachers a low-cost model for a lab exercise and to demonstrate galvanic cells using a paper-based device. As electrodes, metal ions, and electrolyte, respectively, metal strips, metal solutions, and KCl solution are used. In addition to supporting reactions, a paper-based device functions as an electrolyte salt bridge. This article obvious the key points of the paper-based galvanic cell activity, highlighting its cost-effectiveness, simplicity, and versatility for use across various educational levels in the field of chemistry. It also emphasizes the practicality and potential applications of the activity in both classroom demonstrations and student experiments. Moreover, teachers can adapt and customize the paper-based device to suit their specific teaching needs in chemistry and related fields, for broad application and enhanced student learning experiences.
