Tampering detection enclosure

Methods, apparatuses and systems for detecting tampering are disclosed. The methods, apparatuses and systems for detecting tampering can involve positioning at least a portion of one or more ingress/egress line having a first end and a second end in a clamping box configured to provide detection of tampering; and detecting tampering by observing the clamping box.

Tampering detection clamping box for ingress and egress lines

A fuel cell comprises a cathode gas diffusion layer, a cathode catalyst layer, an anode gas diffusion layer, an anode catalyst layer and an electrolyte. The diffusion resistance of the anode gas diffusion layer when operated with anode fuel is higher than the diffusion resistance of the cathode gas diffusion layer. The anode gas diffusion layer may comprise filler particles having in-plane platelet geometries and be made of lower cost materials and manufacturing processes than currently available commercial carbon fiber substrates. The diffusion resistance difference between the anode gas diffusion layer and the cathode gas diffusion layer may allow for passive water balance control.
