Standards, codes and regulations of Hydrogen Refueling Stations and Hydrogen Fuel Cell Vehicles
Bibliographic record
Abstract
The origin of the project appears because of the necessity of the “Laboratoire de pile a combustible” of UTBM University to work on the safety and normative aspects of their project. They work on the field of hydrogen refueling station (HRS) and hydrogen fuel cell vehicles (HFCV). For that reason the objective of this project has been to create an efficient database where all the standards, codes and regulations (International, European, USA, Canadian, French and Spanish) that concerns to their project were collected. In order to reach the final objective, the project begins with a study of hydrogen properties and hazards. This part is very important to understand why hydrogen is considered as a dangerous gas and what is the potential severity of the accidents that it could cause. Then a description of the project parts (hydrogen delivery, hydrogen refueling stations and hydrogen fuel cell vehicles) has been made. In this part, the general characteristics and the principal elements of each one are explained. Before starting with efficient classification of the normative, it has been necessary to do a deep research of all the standards, codes and regulations that concern the project. With them, the first database has been created, where the main information like the title, the abstract, the restrictions and the cost of each one has been collected. Finally, with all this information it has been possible to start with the efficient classification. For that, the two main parts HRS and HFCV have been divided in its different components and all the normative has been organized according to them. A website has been created with the objective of containing all this classification in a useful media where the user can find easily and quickly, and, the most important, from everywhere, all the information that he needs. Moreover, a survey to people from different countries has been made in order to do a social and cultural study about the feelings that people have about HFCV and also to do a normative comparison between standards of different countries and regions, to understand the different perceptions of the hazards.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
