IEEE TRANSACTIONS ON APPLIED SUPERCONDUCTIVITY 29(5) 2019年8月 [査読有り]
We have been developing a liquid hydrogen (LH2) cooled superconducting energy apparatus, such as superconducting generator, SMES, and so on. An MgB2 superconductor whose critical temperature is 39 K is now developing for a practical use. It can he...

<p>A loading system plays a role of loading and unloading liquid hydrogen between a carrier ship and a ground storage facility in hydrogen supply chain in which hydrogen in the form of liquid phase is transported by the carrier ship from a resourc...
<p>To improve safety regulations for fuel cell vehicles and hydrogen infrastructure, experiments of cryo-compressed hydrogen leakage diffusion were conducted. The experimental apparatus can supply 90 MPa hydrogen of various temperature conditions....
<p>JAXA has constructed an experimental facility to pressurize and supply liquid hydrogen at a maximum pressure of 90 MPa to conduct experimental research on the injection of high pressure liquid hydrogen into the atmosphere. Liquid hydrogen has a...
