Title: Innovations by Patricia J Nelson
Introduction
Patricia J Nelson is a notable inventor based in Rochester, NY (US). She has made significant contributions to the field of fuel cell technology, holding a total of 4 patents. Her work focuses on enhancing the efficiency and functionality of fuel processors through innovative sensor systems.
Latest Patents
One of her latest patents is a hydrogen sensor for fuel processors of a fuel cell. This invention provides a method and apparatus to estimate hydrogen concentration in a reformate stream produced by a fuel processor. The sensor measures carbon monoxide, carbon dioxide, and water in the reformate stream, while a fuel meter, air meter, and water meter control the respective inputs to the fuel processor. Additionally, a transport delay estimator recursively estimates the transport delay of the fuel processor, and a hydrogen estimator uses this information to accurately estimate hydrogen concentration. The hydrogen estimator includes a fuel processor model that is adjusted using the estimated transport delay. The measurements of carbon monoxide, carbon dioxide, and water are conducted using a nondispersive infrared (NDIR) sensor.
Another significant patent by Nelson is a relative humidity sensor with compensation for changes in pressure and gas composition. This sensor system is designed to sense the relative humidity level of a gas stream in a fuel cell. It includes a humidity sensor that generates a relative humidity signal, a pressure sensor that provides a pressure signal, and a temperature sensor that offers a temperature signal. A compensator connected to these sensors generates a compensated relative humidity signal based on the collected data. Additional inputs can include gas composition sensors that determine the concentration of various gases.
