CHEMICAL AND ELECTROCHEMICAL CELL ELECTRONICS PROTECTION SYSTEM

An electrochemical system includes a hydrogen diffusion barrier physically separating the system into a hydrogen rich zone and a hydrogen poor zone, an electronic component located in the hydrogen poor zone and exposed to hydrogen diffusing from the hydrogen rich zone, a hydrogen pump, located in the hydrogen rich zone and the hydrogen poor zone, including: a cathode, an anode, an electrolyte separating the cathode and the anode, an anode encapsulation contacting the anode and a portion of the electrolyte, and an external electrical circuit biased to drive H+ current from the anode to the cathode to pump hydrogen diffusing from the hydrogen rich zone into the hydrogen poor zone back into the hydrogen rich zone.
