Abstract
The present invention relates to a unique, compact hydrogen electrochemical system which eliminates the need for explosion-proof equipment. This system merely separates the electrical equipment from the hydrogen source with a wall, but employs a positive pressure, of about 0.1 inches water column, air purge throughout the system to prevent the introduction of hydrogen gas to the electrical equipment and to recover and use waste heat.
