A stationary fuel cell is a device that generates electricity by reforming city gas or LPG to extract hydrogen and supply it to a fuel cell. The generated electricity and exhaust heat are supplied to homes, buildings, and factories near the installation site.
Stationary fuel cells are expected to reduce CO2 emissions as a distributed power generation system for homes, buildings, and factories because of the high efficiency of fuel cell power generation and low power transmission loss compared to conventional power generation. Fuel cells for home use have already been commercialized.
Various types of fuel cells such as SOFC, PEFC, and MCFC (Molten Carbonate Fuel Cell) are used depending on the application of the facility. In the case of commercial and industrial fuel cells, biogas and hydrogen fueled systems are also being commercialized.
In the development of stationary fuel cells, it is necessary to measure impurity gases other than hydrogen during fuel reforming and analyze the effects of these impurities on the fuel cell materials. Furthermore, a comprehensive evaluation of the fuel cell is necessary.
Evaluation of stationary fuel cell
Our fuel cell evaluation equipment is ideal for testing and evaluating fuel cell cells, stacks, and systems for stationary fuel cells. In addition to performance evaluation, durability evaluation and accelerated degradation testing are performed with a high level of safety.
Mixed Gas Generation and Flow Control
In the development of fuel cells, gas mixtures under various conditions are simulated, and the gas flow rates are controlled and supplied to the fuel cells for testing and evaluation. This requires high-precision vaporization, mixing, and flow control devices.
We have flow control technology that is also used in semiconductor processes, and supports fuel cell development and testing with accurate control of gas concentration and humidity.
Real-Time Measurement of Impurity Gas Concentration
The stationary fuel cell system, which generates electricity from hydrogen reformed from city gas, requires desulfurization and CO removal before and after the reformer in order to produce hydrogen with less impurities required for the fuel cell.
Real-time gas measurement of impurity gases contributes to the development of equipment and to the confirmation of normal operation of stationary fuel cell equipment for commercial and industrial use.
Measurement of Various Gas Concentrations and Water Quality
Various gas analyzers to measure the concentration of impurity gases such as CO, CO2, and sulfur gases that lead to the life of fuel cells, and water analyzers to measure the pH of wastewater are contributing to the development of fuel cells.
