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.

[ What is claimed is:] [1.] A hydrogen electrochemical system, comprising:a first zone having a heat exchanger and process control equipment;a second zone having a cell stack for producing or consuming hydrogen and at least one gas outlet, wherein said second zone is adjacent to and separated from said first zone by a wall such that said first zone and said second zone are separately isolated; anda first gas moving device for drawing gas into and creating a positive pressure within said second zone such that the gas purges said second zone, moving any uncontained hydrogen out said outlet.
