We will exhibit the AEM hydrogen generation system at the H2 & FC EXPO.

Adopts AEM (Anion Exchange Membrane) water electrolysis. A water electrolysis device that combines the advantages of alkaline water electrolysis and PEM water electrolysis.

**Three Features of AEM-Type Water Electrolysis Hydrogen Production Device** 1. **Generation of High-Pressure, High-Purity Hydrogen** Hydrogen with a purity of 99.999% can be generated at a high pressure of 3.5 MPaG. The electrode reaction is the same as that of alkaline water electrolysis, but it does not use highly corrosive concentrated alkaline solutions. The cell structure, similar to PEM water electrolysis, features a membrane electrode assembly structure that offers excellent characteristics such as fast response, wide operating range, and tolerance for intermittent operation. 2. **Low Cost Achieved Without Precious Metals** AEM water electrolysis operates in a weak alkaline environment using hydroxide ions as carriers, eliminating the need for precious metals and thus achieving low costs. Additionally, the amount of water expelled from the cathode is minimal, and there is no need for electrolyte circulation, simplifying the system. 3. **Modular Design Allows for Continued Operation Even if One Unit Fails** One AEM stack can generate 0.5 Nm³ of hydrogen per hour with 2.4 kW of power, and multiple stacks can be stacked to achieve MW-class hydrogen production (210 Nm³ per hour and above). Furthermore, due to the modular design, if a single stack experiences a malfunction, only that specific stack needs to be repaired or replaced. This results in less maintenance effort compared to large hydrogen production systems.

HP Inc. will hold the "HP Future of Work AI Conference 2025" at Tokyo International Forum, Hall B. At this event, under the message "Freedom to be particular about how we work," we will introduce the possibilities of on-device AI and its practical applications, along with case studies and technological trends. Whether you are considering implementing AI or have already started using it, you are sure to find hints for your next steps. We sincerely look forward to your attendance.

Our company will be exhibiting at the "15th Agriculture WEEK (J-AGRI Tokyo)" held at Makuhari Messe from October 1 (Wednesday) to October 3 (Friday). In the Livestock Materials EXPO zone, we will be showcasing our popular products for livestock and facility horticulture, including the "retrofit mist system for existing fans in barns/greenhouses, easy-to-install integrated mist system TM" and the "new product, large cylindrical mist system TM," along with related products. We sincerely look forward to your visit. Our booth number is 36-34 in Hall 9 of Makuhari Messe.

Yakeshi Electric will exhibit at the Space Science and Technology Union Conference to be held in November 2025. ■69th Space Science and Technology Union Conference https://smartconf.jp/content/sstc69/ Dates: November 25 (Tuesday) - November 28 (Friday), 2025 (4 days) The Space Science and Technology Union Conference is a large-scale event where people involved in space, including JAXA, various research institutions, universities, and private companies, gather together. Our company develops electronic sources for small satellites (including impregnated cathodes and LaB6) and manufactures peripheral components such as sensors and power supply units. This time, we plan to expand our display of electronic sources and include additional components such as tantalum and Inconel! In particular, electronic sources like impregnated cathodes are often purchased from overseas due to the limited number of domestic manufacturers, which can lead to difficulties in fine adjustments and flexibility. However, our company offers: ● Control of porosity and selection of emitters ● Manufacturing according to desired sizes and shapes ● Production starting from one unit ● Stable domestic procurement We can provide solutions tailored to your research and development needs! Please feel free to consult with us.

We will introduce an overview of "IATF16949:2016," which is an essential requirement for entering the automotive industry, along with key points considering the current situation of industry trends. In planning for certification of sector standards, we have structured the training content for companies that are gathering information on what to do first and planning to obtain certification. * We have received inquiries from business partners and are struggling to respond. * We are planning to obtain certification but do not fully understand the specific preparations and initiatives required. This seminar is recommended for companies seeking to acquire knowledge and gather information about sector standards.
