Title: **Innovator Nobuo Nagasaki: Pioneering Fuel Cell Technology**

Introduction

Nobuo Nagasaki, an accomplished inventor based in Hitachi, Japan, has made significant contributions to the field of energy innovation. With a portfolio of three patents related to integrated power plants and fuel cell technologies, he continues to push the boundaries of what is possible in sustainable energy solutions.

Latest Patents

Nagasaki's latest patents include an "Integrated Power Plant and Method for Operating the Plant" and a "Fuel Cell Power Plant." The integrated power plant leverages a molten carbonate type fuel cell in combination with a gas turbine system, which consists of a gas turbine, a steam turbine, and a common generator. This innovative design heats the reformer for the fuel gas by using the cathode off-gas from the fuel cell, providing the necessary heat for reforming. Interestingly, a portion of the anode off-gas is combusted in a separate burner to create CO₂ recycling, while the bulk of the remaining gas is supplied to the gas turbine combustor. This configuration allows existing gas turbine systems to be utilized without substantial modifications, enabling the fuel cell power generation plant to be seamlessly integrated as an auxiliary unit.

The second patent, a "Fuel Cell Power Plant," features a design that employs a molten carbonate electrolyte and includes a reformer for transforming fuel into a reactive gas for the anode. It incorporates an expansion turbine connected to a compressor and a combustor for burning exhausted gases. A unique aspect of this system is the additional combustor, which enhances overall thermal efficiency by burning unburned gas from the anode exhaust with the cathode exhaust gas.
