Fuel cell technologies Part 2.100: Fuel cell modules – Safety
The objective of this standard is to deal with conditions that can yield hazards to persons and cause damage outside the fuel cell modules.
This document does not address protection against damage inside the fuel cell modules provided such damage does not lead to hazards outside the fuel cell.
This standard was prepared by the Standards New Zealand P3652 committee and has been reproduced as a modified adoption of IEC 62282-2-100:2020; Fuel cell technologies – Part 2-100: Fuel cell modules – Safety.
