Description
Purshottam Assudani and co-authors improve tiny aluminum-air fuel cells by changing their paper channel in a 2026 study. These microfluidic cells promise cheap, compact power for portable gear, and their output hinges on how the electrolyte moves through the paper strip inside. The team swapped the standard cellulose paper for glass fiber paper and compared the two.
Glass fiber's open network sped capillary flow and resisted the alkaline electrolyte better, feeding the cathode more evenly. With a mid-strength potassium hydroxide solution, the glass fiber cell peaked at about seventy-three milliwatts per square centimeter, nearly double the cellulose version, with stable discharge under steady load. Impedance tests showed lower losses at mid-range strengths. Substrate choice alone gave the gain.
