Apparatus and method for measuring hydrogen concentration using temperature sensors

A method for determining a hydrogen concentration using a plurality of temperature sensors, the method comprising:

• measuring, by heating a plurality of heating elements, a plurality of heating element measurement values including at least one of a temperature of an individual heating element, a resistance of the individual heating element, or a time constant of the individual heating element;
• measuring a temperature of an external gas insulated from the plurality of heating elements;
• and
• determining a hydrogen concentration based on the plurality of heating element measurement values and the temperature of the external gas.

An apparatus for determining a hydrogen concentration using a plurality of temperature sensors, the apparatus comprising:

• a plurality of thermal conductive temperature sensors configured to
• heat a plurality of heating elements, and
• measure a plurality of heating element measurement values, including measuring, for each of the plurality of heating elements, at least one of a temperature of the heating element, a resistance of the heating element, or a time constant of the heating element;
• an external temperature sensor configured to measure a temperature of an external gas insulated from the plurality of heating elements;
• and
• at least one processor configured to determine a hydrogen concentration based on the plurality of heating element measurement values and the temperature of the external gas.
