PRODUCTION OF HYDROGEN THROUGH SEAWATER ELECTROLYSIS USING AN EXPERIMENTAL PROTOTYPE.

Hydrogen is a product that has been on the rise over the past decade. Its primary use is as a raw material in industry, but it is also emerging as a provider of electrical power and fuel. A laboratory-scale electrolysis cell was used with seawater employing stainless steel electrodes. Hydrogen production was measured using an electrochemical sensor and an alternating current power source to measure current intensity. A voltage was established in a range of 1,5 to 20 V as the operating condition. The current density (j) behavior in the electrolysis cell increased with increasing applied voltage. Current density ranged from 0,07 A/cm2 to 3,15 A/cm2. Hydrogen production efficiency was achieved from 2,5 V onwards, indicating that reaching 1000 ppmH2 was accomplished in 53 and 34 seconds at voltages of 15 and 20 V, respectively. The results demonstrate direct electrolysis with seawater and its utilization with a renewable energy source. [ABSTRACT FROM AUTHOR]
