Title: **Paul E Grevstad: Innovator in Fuel Cell Technology**
Introduction
Paul E Grevstad is a prominent inventor based in West Hartford, CT, with a notable portfolio that includes six patents. His innovations primarily focus on fuel cell technology, contributing significantly to advancements in energy systems used in various applications.
Latest Patents
Among his latest patents, one is titled **"Process for Adding Electrolyte to a Fuel Cell Stack."** This patent describes a method where electrolyte is replenished within a fully assembled stack of fuel cells. The process involves depositing a dilute electrolyte on an external vertical face of the stack, allowing it to be absorbed through capillary action. The electrolyte is continuously applied until the entire stack is saturated, after which the stack is heated to evaporate water, achieving the desired operable volume and concentration of the electrolyte.
Another significant patent is the **"Method for Producing a Fuel Cell Manifold Seal."** This invention addresses the challenge of maintaining a low leak rate seal between the manifold and the fuel cell stack, particularly as the stack experiences compressive creep. Grevstad's innovative seal system utilizes a polymer seal frame that adheres to the stack, ensuring it moves cohesively without resulting in destructive sliding at the rough stack interface.
