A5. Description of work scope
The work was divided into five sub-tasks (5.1 to 5.5). The details of the experimental tests were decided through WP1 and subsequent strategy document developed as sub-task 5.1 entitled ‘Experimental strategy document’. The overall approach was initially broken down into fuel supply/storage (5.2), failures within the fuel cell enclosure (tasks 5.3 and 5.4) and detection within the enclosure (task 5.5). Finally the full list of scenarios which were accepted for detailed experimental study is presented in the following table:
