Is is possible that I travel alone without my wife.
No (since she is not in the UK already)
Or is it okay that I take my wife EU passport along with me to show.
No
Generally, if the premise of your visit has changed, you can't use visas or other documents obtained for a different premise.
A family permit will be issued if the applicant is the spouse, civil partner or dependent child of an EEA national and they will be travelling to the UK with that person
The UK government say:
The EEA citizen youβre joining must either:
- be in the UK already
- be travelling with you to the UK within 6 months of the date of your application
(my emphasis in both quotations above)
Travelling with your wife's passport is not the same as travelling with your wife.
As a (presumably) non-EU national you need to apply for an appropriate visa if one is required for your nationality.
