With a total of 3 patents to her name, Petitjean is recognized for her innovative approaches to energy solutions.

Latest Patents

Among her latest patents is a water electrolysis system (SOEC) or fuel cell (SOFC) that operates under pressure in a tight enclosure with improved regulation. This system is designed to regulate the DH wet gas flow upstream of one of the chambers to ensure the electrochemical stability of the predetermined operating point. Additionally, it regulates the DO gas flow upstream of the second chamber to ensure gas scavenging and safety within the enclosure. The system also includes mechanisms to control the pressure of gases, including wet gas, which are generally hot.

Another notable patent is a method for operating an SOEC-type stack reactor for producing methane in the absence of available electricity. This method involves injecting synthesis gas or a mixture of hydrogen and carbon monoxide at the cathode inlet of the reactor to produce methane. The exothermic nature of the catalytic methanation reaction allows the stack reactor to maintain temperature without fuel loss.
