Title: Innovations by Jonathan Puhalski
Introduction
Jonathan Puhalski is an accomplished inventor based in Winsted, Connecticut. He holds a total of 3 patents that focus on advancements in fuel cell technology. His work has contributed significantly to the efficiency and performance of fuel cells, which are crucial for sustainable energy solutions.
Latest Patents
One of his notable patents is for a fuel cell having a hydrophilic substrate layer. This innovation includes a membrane electrode assembly (MEA) situated between an anode support plate and a cathode support plate. The design ensures that the pressure of the reactant gas streams is greater than that of the coolant stream. This configuration allows for a greater percentage of the pores within the hydrophilic substrate layer to contain reactant gas rather than water. Consequently, any water that forms on the cathode side of the MEA migrates away from the MEA, enhancing the electrical efficiency of the fuel cell.
Another significant patent by Puhalski involves a fuel cell with interdigitated flow channels and water transport plates. This design features porous water transport plates or support plates with interdigitated flow channels for reactant gas streams and conventional flow channels for coolant streams. The pressure differential between the reactant gas streams and the coolant stream allows for improved mass transfer of gases into the support plates, thereby increasing the electrical performance of the fuel cell. Current densities of about 1.6 amps per square centimeter are achieved with air stoichiometries not exceeding 2.50.
