Characteristics of Albumen bio-electrochemical cell for low power applications

I S Yahia, H. Y. Zahran, K. F. Khaled

Abstract


Albumen cell is fabricated and characterized for the first time. The electrical properties of Zinc/Albumen/Carbon are investigated. In this cell, albumen as an electrolyte is used, while zinc and carbon rods are the two electrodes of the cell. The current–voltage load characteristics, charge voltage/current–time and discharge voltage/current–time are measured. The power curve shows a maximum peak for zinc/Albumen solution/carbon and the values of the maximum power approaches 0.1307 mW at 0.309 V. The extracted electrical parameters such as open circuit voltage, short circuit current, electrical energy and the capacity of the albumen cell are 0.91 V, 0.512 mA, -175.606 kJ/mole and 26.568 kC (7.38 Wh), respectively. It is clear from these measurements that albumen fuel cell is stable and rechargeable. The cell can be used in the applications of low power source, sensor, bio-sensor and bio-electronic applications.
