Toyota Develops Packaged Fuel Cell System Module to Promote the Hydrogen Utilization



Toyota  Motor  Corporation Toyota Develops Packaged Fuel Cell System Module to Promote the Hydrogen Utilization toward the Achievement of Carbon Neutrality Integrates Main Components such as Fuel Cell Stack into Compact Package, Making it Easily Adaptable to a Variety of Products Toyota City, Japan, February 26, 2021―Toyota Motor Corporation (Toyota) has developed a product that packages a fuel cell (FC) system into a compact module and plans to begin selling it in the spring of  2021  or  later. The  new  module  will  be  easily  utilized  by  companies  that  are  developing  and  manufacturing FC products for wide variety of applications, including mobility such as trucks, buses, trains and ships, as well as stationary generators (referred to hereafter as "FC product companies").  As  various  policies  for  utilizing  hydrogen  have  been  adopted in  recent  years  in  each  country  and  region and many companies have been entering the market one after another. As a result, the need for hydrogen and FC technologies has been increasing in a variety of applications. In addition to its effort to popularize FCEVs, Toyota will continue to strengthen its initiatives as an FC system supplier to promote hydrogen utilization through the popularization of FC products together with various FC product companies with the aim of reducing CO2 emissions to curtail global warming and to contribute to the achievement of carbon neutrality. Toyota has been taking various initiatives toward the creation of a hydrogen society, such as selling the "Mirai"  FCEV and the "SORA"  FCEV bus, selling FC systems to FC product companies, as well as  allowing  royalty-free  use  of  its  FCEV - related  patent  licenses.  Through these experiences,  the company  has  learned  that  many companies  involved  in  FC  products  in  a  variety  of  industries  are looking for FC systems that can be easily adapted to their own products.Therefore, to address  these  needs,  Toyota has developed a  product  that  packages individual  FC system-related products of second generation Toyota Mirai with enhanced performance, such as the FC stack, as well as components that handle air supply, hydrogen supply, cooling, and power control, into a single compact module. The new module is available in four models―a vertical type (Type I) and a horizontal type (Type II), with rated output of either 60 kW or 80 kW. 

2 / Toyota developed the FC module utilizing technologies it cultivated through its development of FCEVs over  many  years,  as  well  as  the  knowledge and expertise accumulated  in  a  variety  of  usage  environments around the world and utilized in the Mirai. The following section describes the specific features of the module:1.

The new module has a wide voltage range (400 to 750 V) and can be directly connected to an existing electrical instrument provided with a motor, inverter, and battery, etc., thanks to a built-in, dedicated  FC  boost converter  that  simplifies  the  development  and  manufacture  of  FC products. In addition, the system's  modularization greatly improves convenience.-The four module models can be combined according to the application, flexibly adapting to the output level and amount of installation space available. -Modularization  eliminates  the  need  to  create  designs  for individually  installing  FC  system-related components  and  to connect individual components.  It   also  integrates  and decreases the number of locations the module must be connected to a device, allowing for easy installation.

Excellent safety/reliability and support structure for peace of mind during use-To  ensure  safety  related  to  the  use  of  hydrogen and  high  voltage,  the  countermeasures cultivated during  the  development  of  electrified  vehicles  such  as  FCEVs  and  HEVs  were implemented.  These  measures  are  based  on  the  basic  approach  of  ensuring  that  hydrogen does not leak and, in the unlikely event that any leaks should occur, ensuring their immediate detection and stoppage.-The module was designed to work in a broad range of operating environments, ensuring system operation at low or high temperature, at higher altitude where the oxygen level is lower, and under applications involving vibration.-When FC product companies decide to utilize the module, they have the option to request the support of highly experienced engineers in determining optimal layout and design according to fuel economy, usage duration, and running cost, etc.3. Excellent basic performance (high output and economical efficiency)-Capitalizing  on  the  characteristics  of  the  compact  Toyota  FC  system,  which  eliminated  the  humidifier by circulating the water generated during power generation inside the FC stack, the new module has achieved a world-class, top level output density per unit volume.-The maintenance requirements of the new module are simple and infrequent, helping to reduce the total cost, from procurement and usage, to disposal.*This module is scheduled to be exhibited at the Fuel Cell Expo (FC EXPO) to be held at Tokyo Big Sight (Koto-ku, Tokyo) from March 3-5, 2021. 

4 / 4Toyota  Motor  Corporation  works  to  develop  and  manufacture  innovative,  safe  and  high-quality  products  and  services  that  create happiness by providing mobility for all. We believe that true achievement  comes  from  supporting  our  customers,  partners,  employees, and the communities in which we operate. Since our founding over 80 years ago in 1937, we have applied our Guiding Principles in pursuit of a safer, greener and more inclusive society. Today,  as  we  transform  into  a  mobility  company  developing  connected, automated, shared and electrified technologies, we also remain true to our Guiding Principles and many of the United Nations' Sustainable Development Goals to help realize an ever-better world, where everyone is free to move.SDG's Initiatives: goals that this project makes particular contribution to:
