Electrochemical cell catalyst state of health monitoring device

An electrochemical cell for monitoring catalyst state of health, the electrochemical cell comprising:

• first and second electrodes including first and second catalyst materials, respectively;
• a polymer electrolyte material extending between the first and second electrodes;
• a first magnetic device adjacent a first side of the first catalyst material;
• and
• a second magnetic device adjacent a second side of the first catalyst material, the first or second magnetic device configured to generate a magnetic field, the other of the first and second magnetic devices configured to receive a magnetic response from the first catalyst material in response to the magnetic field, the magnetic response indicative of magnetic response data of the first catalyst material indicative of a state of health of the first catalyst material.

A method of monitoring a state of health of an electrochemical cell, the method comprising:

• operating an electrochemical cell having first and second electrodes including first and second catalyst materials, respectively, and a polymer electrolyte material extending between the first and second electrodes;
• generating, via a first magnetic device, a magnetic field during the operating step;
• receiving, via a second magnetic device, a magnetic response from the first catalyst material in response to the magnetic field during the operating step;
• and
• determining magnetic response data of the first catalyst material in response to the magnetic response, the magnetic response data indicative of the state of health of the first catalyst material.
